Everything was perfect! They upgraded our room to an Ocean view villa and the room was beautiful! The bedding sheets were soft and comfortable . Parking is available onsite. Area is quiet and mini version breakfast served. Room was clean and well air-conditioned. There’s an on-site restaurant, pool with other shops within walking distant. Highly recommend!

Loved the property and would stay again in a heartbeat. Staff and location is top notch. Owner is lovely and the attached cafe is great. Even if all that weren't true, the view alone would be worth the price of admission.
