After reading some of the comments about a moldy/stuffy smell in the apartment I was a bit worried. But it wasn't so bad as expected, so for me all was fine. I went in December and it was pretty cold in the town. The heating in the apartment didn't do much, so it was a bit chilly inside unfortunately. The apartment is directly on a small alley. You can hear all noises from outside very well, but it wasn't really disturbing (only people chatting etcetera).
All in all it's a tidy, nice and spacious apartment and it was a good stay!
