Positives: The bathroom here is the main attraction. It lives up to and goes beyond the photos and description. The shower is amazing. The tub was big enough to fit me (at 6'2"). Kitchen is nice (with necessary kitchenware) and the living room is good (there's a small pull out couch). Washer and dryer worked perfectly. Bed was very comfortable.
Negatives: There is only a small AC unit in the bedroom that does not do a great job at cooling the bedroom. Combine that with the house rule that the AC should be turned off when the room is not in use, and it's going to take forever to cool off enough to fall asleep. Every other room (bathroom, kitchen / living room) was incredibly hot the entire time. There are little fans in the kitchen/living room but those more or less just circulate the hot air without cooling anything down.
Overall: I think this is a good spot when it's not incredibly hot. It does live up to its name if you're looking for a "spa"-type weekend. The tub was definitely my favorite part of the airbnb.
