100% verified reviews7.0 / 10.0Good·Mar 2026
The property was very attractive. The rooms were good size and well appointed
There was only one bathroom on the property that was near the office. No bathrooms at the pools or Tiki bar. Long walk from adult pool. No amenities. No service at the pools for drinks. No breakfast on site. Had to order the night before for delivery to your room. Over priced.
10.0 / 10.0Outstanding·Mar 2026
The facilities were amazing. It was also much quieter than I was expecting
Nothing really. Staff were just okay. There were more than a few who were unfriendly and a little icy but overall still a positive existence.
9.0 / 10.0Outstanding·Feb 2026
It’s tranquil.
We stayed in a 2 queen sized bed room. It was huge! So, the only comment that I’d make is that they need to put a small dining table & chairs in there. There’s certainly enough room.
6.0 / 10.0Average·Jan 2026
Good location, near to several Keys attractions.
Few amenities for the cost. Large room but only one arm chair. Bar and restaurant close at 9pm - not joking!
