Guests who stayed here loved

“We absolutely loved the location, could walk to so much in the area. Also the bikes available to ride were so much fun. We rode for miles along the beach and really was a highlight to our trip. We walked to dinner every night and really enjoyed seeing the ocean on the walking path. The property was very quiet and seemed less touristy then the other resorts down the road. It felt like home to us and we were actual sad to depart for our airbnb up north. The restaurant and bar were not open and didnt look to be opening anytime soon. We were expecting it so that was somewhat of a disappointment. A positive to it though was less people on site :)”
