I have mixed feelings about this, and I really try to save an negative feedback unless really warranted, so I'll try to be thorough.
The Pros: I loved that this was in the heart of Chinatown culture. I felt very safe and there is easy access to the L. The locks and doors felt fairly safe, as well. The bed, linens and floor were clean, which is very important. There were no foul smells, no smell of smoking, and no excessive noise (although I could hear my neighbor talking for several hours while trying to sleep.) The host was kind and fairly responsive. He allowed me a 1 hour late checkout, which helped me out considerably. There were towels and soap.
The Cons: We had no hot water in the shower on our end (it's shared by our wing) the first night. We let it run for about 5 minutes (being an old building, we thought that might help), but it never got hot. After messaging the host, he responded by calling me back (after about 15 minutes) and let me know we could use the shower in the other wing. We were already in bed by then.
The hot water was back on the next day, which was appreciated. The bathrooms were decent, but there was mold in the trim of one, and many long, black hairs in both. It's clear (especially from reading other reviews) that the cleaning regimen needs greatly improved.
The bottom bunk was fairly comfortable, but the upper one was very thin and not comfortable. The curtain is too thin and light shines in all night from the streetlights, making it difficult to sleep. Also, the room is VERY small, with only a few feet from the side and ends of the bed. The bed is noisy and the walls are thin, so it was difficult for this light sleeper. Also, there is no individual climate control (it is shared and controlled elsewhere.)
There are really no small touches added to this place. Not that I really expect it at this price point, but at a time when several AirBnB's are competing for my dollars, I'm going to gravitate to ones who at least have small, thoughtful touches of hospitality.
In the end, I realize my expectations are high for the price point, but I hope the feedback is helpful.
