Wonderful staff ! You can tell the owners go out of their way to make your stay a nice stay every time. Great location, I’ve always found it clean & I always sleep great on the bed. Unfortunately sometimes other guests lack respect & may cause loud noises. I even had my curtain opened, multiple nights by the same woman. Of course that’s not the fault of the property; but unfortunately it’s a potential to interrupt your sleep. I will stay again.

The location couldn’t have been more perfect and despite it being a holiday weekend the parking lot/BNB never felt crowded. Everyone we encountered was lovely and helpful, and the room was a perfect place to take a midday nap or unwind after hours on the beach! We would definitely stay again.

Very cool place to stay; nice pool and quick access to the beach. My cabin was comfortable, clean and perfectly cold for the summer. The staff I interacted were all very pleasant and helpful. Great place to stay.
