"We cannot recommend Kathleen and Marina highly enough! They both patiently showed us properties in Aventura. They both have a unique and specialized knowledge of the area and they share their knowledge with a very confident and common sense approach. There are many fine realtors in town, but these two are in a league of their own. When it comes to knowledge, integrity and patience, I highly recommend Kathleen and Marina. "
