We stayed at this hotel when we went down to Miami to meet with various vendors to discuss our upcoming wedding in the keys. We were very impressed by the Besty, from the cool clean beautiful lobby to the smiling and always attentive staff. We booked a basic category room, and were pleasantly surprised by how nice it was.
The only issue we had was met by immediate reactivity by the property management. The shower drain was clogged and backed up severly in a matter of minutes when I was taking a shower early in the morning. They offered me a key to an available neighboring room so that I could finish my shower, and then actually had the shower drain completely repaired by 9am that morning.
The rooftop bar is amazing. It's peaceful and relaxing with great oversized furniture, and an uninterupted view of the ocean. Also, if you want to be able to get some sleep after a night out at the clubs, this is one of the only hotels far enough away from the noise to be quiet at night.
