The room was clean and comfortable. Staff were helpful. We most enjoyed the hotel's location which was quiet, felt tucked away but very walkable and convenient to nearby restaurants, foodtruck, and stores. The oceanfront was absolutely beautiful and watching sunrise every day was a highlight. of our tripsunshine

Everything else is great other than the Wi-Fi connection. Can only login couple of times - even in midnight the connection fails consistently. My guess is the server only allows certain number of devices to login for the whole property. Then in the room both Verizon and T-Mobile cell phone signals are next to none. We literally had a very quiet vacation disappearing from the grid because kids even had a hard time to contact us. Hope management can invest some money to improve the Wi-Fi system.

Location was great, ocean view and chairs were nice. Room is pretty bare bones and the restaurant being closed felt like we were missing out on drinks and meals on site. Chickens will likely wake you up early each day but they were fun to watch running around. Pool was nice to hang out around outside.
