The unit, itself, was clean and modern. As others noted, it is the bottom unit of a two-story duplex. We didn't have a problem with this.
We were a bit disappointed in the amenities. We only received 3 towels for a group of 4 for our 2-night stay. There were also no additional blankets or linens, except for the comforters on the beds. There were only a sheet or two of paper towels on the roll and no additional rolls. Also, we could not locate any utensils for grilling. We made do but found this unit to be less stocked than most.
The unit is situated in a pretty tight, shallow cove. The swimming conditions weren't great (lots of seaweed and less than 5' of water). We were just feet (literally a few feet) from neighbors' docks and other renters. It was a little more crowded than we were used to.
Overall, though, the unit was nice and clean, and the host was easy to work with. I just felt it was worth mentioning the above.
