The apartment is a nice place for a single person for a few nights. The hosts were very nice and understanding, and extremely flexible with the check in and check out. The downstairs area has enough room to move about, however, the stairs are very steep and small and can be a bit dangerous if you're not careful. Once upstairs, the space can be a bit tight, especially for someone who is taller. You have to sit sideways on the toilet, but the bathroom was very clean and this is a great plus. The shower did not have hot water when I used it although, that may be perhaps due to the time of day that I showered. The sheets on the bed were a bit outdated, but it was comfortable to sleep in. Sometimes, people in the other apartments around or on the street can be noisy at night (this was one of the two nights that I stayed there) and the noise from the outside doors can sound very close to the apartment you're staying in (There were a few times I thought someone was trying to come into the apartment.) The lock to the apartment door gets stuck often and is very hard to get sometimes, you have to find a special way to lock it.
This apartment was nice for a few nights, and I would stay here in a pinch, but not for a long stay. The location of the place is phenomenal, close to the metro and very very central. Great for walkers as well.
