"From check in, to the pool bar, to BB at the outside cabana sports area, the staff was awesome. Location is great, even during lobster mini season. Everything you could want or need you can do right there at the resort. Room was super clean and everything was just nice and relaxing. Could not recommend ..."

"This is a fairly clean place. It has a great location to the water with jet ski rental at the property. The only real issue is the rooms are extremely noisy. We could here every step of the occupants above us and the highway noise was very loud in the room."
