We never actually saw the host (his friend let us into the apartment) because we only spent one night and he worked late, but he was very responsive to questions.
It's definitely a bachelor pad, very sparse, and with some mild odors in the living room. He seemed to be pretty new to airbnb and there were a lot of essential things missing: no bath mat, hand towels, bath towels, or trash can in the bathroom. No top sheet on the mattress. He did provide one bath towel (for two of us) when we asked, though he seemed surprised to be asked for it. He seemed like he wanted to improve things, so hopefully he'll add some of those necessities for future guests.
There is a train that goes very close to the apartment, though the windows are think and the noise wasn't bad with the windows closed.
The mattress is a very thick memory-foam-style that you really sink into. I don't like that kind of mattress very much, but it's partly personal taste.
