Negative: The mattress wasn't comfortable for me because it bounced around a lot, and the bedrooms couldn't be fully darkened—only the living room could.

Positive: This place exceeded our expectations as the photos online simply don’t do it justice. In person the beach area is much larger and cleaner than it appears in the pictures and the rest of the outdoor space is equally impressive…it’s rare to find a property in the Florida keys with this much well maintained outdoor space and beach access
Negative: The check in could be a little sooner say 2-3pm..
Summary: Excellent and all the staff are very customer service oriented
