The grounds are stunning, the pool was well maintained and ocean views are breathtaking. The staff were attentive and helpful. The rooms are comfortable and clean. The location is great if you are planning to spend time on the north and south shores, helps reduce driving times if you are planning to be very active!
It’s a very very budget accommodation. The pictures of the rooms make them look much nicer than they are. That being said, it was fine for one night before heading up north.
Room was spacious with great ocean view. No elevator.
