I’m incredibly grateful to have had Sophia and Tatiana as our agents. From the very beginning they demonstrated an exceptional level of dedication and care in helping my boyfriend and I find our perfect home. They took the time to truly understand our needs, preferences, likes & dislikes, always ensuring every property we viewed was a potential place for us. Beyond their professional skills, this duo showed genuine love and affection in their work and made us feel so valued and cared for as clients and friends. We cannot thank enough for their outstanding service and support.

When people think about Real Estate representation in Miami, one must always expect the best and Sophia Costa goes above and beyond as a realtor! She demonstrated the highest level of professionalism and showed compassion and understanding to my personal needs in finding the perfect apartment. She is immensely knowledgeable about the Miami area and her attention to detail showed me that she is dedicated to helping her clients find the perfect place. Not knowing the Miami area can be tricky to navigate, however, whether you are new to the area or just looking for a different place to live, I would recommend Sophia as a realtor to be there with you on the journey from the beginning to final closing.

We had a lot of luck in finding Taty - we highly recommend her. This is our second transaction with her and we couldn’t be happier that we finally bought a home in the USA. She was always pleasant with a smile on her face and fiercely stood up for our interests. She looked out for every detail for things most realtors don’t usually do, without question going beyond her call of duty, anytime it was needed. Thanks Taty!

There’s just no other way to say it other than Tatiana is the best at what she does. We could not be more grateful for her professionalism and support through the tough process of purchasing our dream home. Taty always had our back and looked out for our best interest always. She went above and beyond every step of the way. She was with us from day one through the entire process and celebrated with us at the end. I would HIGHLY recommend her to anyone and everyone. She made a tough process easier by always being positive, professional and sooooo knowledgeable. You need a lion like her on your side who will go up to bat for you yet with the kindest soul. So professional and knowledgeable, I cannot say it enough! We love working with Taty!

Taty helped us with the sale of our condo and the purchase of our dream home, an off-market property. She was relentless every step of the way until she got the job done. She remains actively supportive to us with any and all questions we have, even if not directly related to the transactions. We have confidently referred friends and family to her who are equally happy with her work. We will remain loyal clients. Thank you Taty!

My wife and I have moved into two different apartments in the Miami area and Tatiana has found us our home both times! She was patient, understanding and really worked to our best interest. She protected us throughout each process and made sure that ultimately my wife and I found what we were looking for and were happy. I trust Tatiana and will continue to work with her - she’s great at what she does!

Taty has been very helpful for our family to find the perfect place. She understands what you need and finds the perfect fit. She is also very dedicated and follows up to make sure you are feeling great at your new place. I would definitely recommend her.

Complete. That would be the definition for Taty. Impeccable professional. Thanks to her, I stopped doing a terrible business when choosing my apartment in Miami. With her expertise and sensitivity, she directed me to a property ten times better to live , and with guarantees of future gains. Taking care of the whole process, she helped me with the purchase, in the renovation and now in the maintenance. Never measured efforts so that I always had the best. Any and all problems that I had and I have, in a maximum of 2 days it solves. Incredible. Really a professional very dear to me and my wife, we literally, gave her the key to our house.

Tatiana helped my sister and I find the perfect waterside apartment in Brickell on a budget! She was available at all times of the day (until our new lease was signed). Her assistance was instrumental in securing a great deal on a Brickell apartment NEXT TO THE WATER! Will be using Tatiana for ALL of my Miami real estate deals.

Taty is absolutely the best. She is knowledgeable and is always on top of every detail. She really understands your needs and does whatever it takes to get it. Impressive. But more importantly she is an extraordinary person. I am grateful for what she did for us in this difficult market.

Taty, is a professional! She is honest and efficient and understands this insane & highly suspect Miami real estate market. I highly recommend her to accompany and represent you on finding a home in South Florida!

There is no other way to describe Taty other than she is hands down the BEST AGENT in Miami/Florida. I am so glad we met because without her we would have never found our new rental home. She is a go getter! The market is moving so quickly right now and we were having such a hard time finding a unit (by the time we would reach out units were already gone) and Taty remained persistent, calm, and always was honest with us which we appreciated because otherwise we would have panicked and settled for a unit we did not love. We dealt with many other agents in the beginning and stuck with Taty because we could trust her - her professionalism and hard work are unparalleled (she often times would wake up in middle night to make sure we got our offers in ASAP). Taty never overlooks any details and ALWAYS looked our for our best interests and had our backs. She helped us find a place we LOVE and I guarantee if you go with her as your agent you will have the BEST experience possible!!

Excellent professional, he has helped us throughout our process of arriving in Miami. I continually look for apartment alternatives, always thinking about the best comfort for our family. Furthermore, whenever we asked her for advice such as schools, traffic, pediatricians, cars, etc... she tried to give us objective and clear information. Without a doubt, I will count on her as my real estate agent in Miami. TOP 100%

Effective, to the point without losing empathy and psychology to handle both buyers and sellers. Sharp negotiator. Top professional, a win-win experience. Even does follow-ups. Can’t recommend her enough.

Sophia was an incredible help during the purchase of my first condo, and I truly couldn’t have done it without her. From the very beginning, she made everything feel less overwhelming by clearly explaining each step of the process and guiding me through every decision. Her recommendations were spot-on and always made me feel like I was in good hands. What stood out the most was her constant support—she was there throughout the entire buying journey, especially during the closing, which can be a stressful time. She also walked me through the long checklist of items needed to complete the purchase, making sure nothing was missed. Sophia made what could have been a complicated experience feel smooth and manageable, and I’m so grateful for her expertise and patience. I highly recommend!

If you're looking for knowledgeable and dedicated real estate agents in Miami, I highly recommend Sophia and Tatiana!

I wasn’t planning on writing a long review, but Sophie was too great to work with for me not to. My move from New York to Miami had a lot of unknowns, and at first i was just trying to get a feel for the market. Sophie was very straightforward from the beginning; no pressure, just clear guidance and honest input, which I appreciated. At one point I ran into a few timing and logistics issues, and that’s when I was so happy to have her. She handled things quickly, stayed on top of everyone involved, and didn’t let anything drag. It felt like she was always one step ahead and very responsive. She also has a very calm way about her. Even when things got a bit hectic on our end, she kept everything grounded and manageable. Overall, just a really great experience. She is professional, reliable, and easy to talk to. I highly recommend Sophie.
