Great place to stay overlooking the water with nice pool. Staff is great. Location is great, close to everything but not in the middle of the craziness of Duvall Street. Room was good. General property could use some sprucing up but doesn’t take away from the overall pluses of the place.

Convenient location. Staff very friendly and accommodating. Nice view. Seaside cafe was great. Moondog pastries available for breakfast. Insulation probably not great and could hear roosters crowing at night even on the top floor.
