Very Good

Less busy area, which was nice to get away from the crowds. Comfy clean king bed. Limited hot water in the shower all three days. Convenient water and ice-filling station in the lobby. Loved the ability to rent cruiser bikes. The room and lobby were simple. The view and balcony from the one-bedroom was not as great/comfortable as pictures make it out to be. No direct access to the beach from the property, though the area isn't really swimmable there.
Everything was amazing except for the shower water pressure wasn’t there and the water didn’t warm up enough… very quiet place and will like to come again
Beautiful setting. Grounds were pristine. Pool inviting. Great location. Quiet and only the sound of the waves. Beds were comfortable. Breakfast foods to go were well stocked. Coffee pot, and coffee in room very good.
Great location right on the ocean. Stayed in the older section above the restaurant which was fine however they have music every night from 7 to 8:30. which reverberated up through the room. The food and service at the restaurant, "The Bull Shed" was excellent. Grounds were maintained beautifully.
We loved that if was so quiet and the ammenities were outstanding. The oceanside room was so relaxing and beautiful sunrise. Highly recommend. We will definatley stay here again. Kuddos to Roberta at the front desk for being helpful.
