I enjoyed my stay, the apartment was very clean and taken care of. My room was big enough and had a lot of light from 3 windows. The batjroom was clean as well. The fifth floor is not a big deal especially if your are young and like to walk anyway - no big deal. The hosts were open to special requests and aways answered immediately.
The location was o.k, depending on what you are looking for. 5 minutes walk from the subway, 3 min walk to the bus, and just outside the building there a rentable bicycles.
