This place is great! The room had everything we needed to make small meals, the lobby has a shelf for people to leave things which has lots of useful things (make sure you check)! The garden and the cats are cute and the location is perfect. It also has a great traditional South Beach feel. We highly recommend it!

The property was advertised to have a private white sand beach which is why I made the reservation. It was covered feet deep in seaweed. Granted there are things out of the property's control, but there should have been a warning on their website that the beach may not be available for use. Also, we were given two small individual size packets of coffee for a twelve cup coffee maker for four days. I went and bought a bag of coffee but then realized there were no other filters either. I enjoy waking up early, and reading outside. The last morning, the staff was out landscaping and hosing off the patio and lounge chairs next to me. I got overspray blown in my face.

Disappointed in room, we've stayed here many, many times and this was disappointing. Also, the amount of people that use the amenities that are not staying at resort OR paying resort fees.
