There is a humidifier but it can't keep up. We even emptied it during our ~2 nights. It's like a greenhouse in the unit and the basement bedroom is even more humid. Also the shower drain was so slow that as soon as you turned on the shower the whole thing would start to flood. The downstairs sink also did not drain well and would still be full an hour later. I have communicated this issue to the host but I'm not sure if this is an issue as it's a basement bathroom. I would also note that the lighting in the basement bathroom is hard to get ready with. Everything else was great. Good location, comfortable bed, clean - we only used the fridge so I can't speak to the rest of the kitchen but the upstairs sink seemed to work fine.
