The apartment was very nice and clean, the location is superb, very close to the city centre and 15 minutes by walking from the railway station. I wouldn't recommend it for longer than 3 nights, as it's quite small. But it's ideal for 2-3 nights.
However, there was a problem with shower, it was broken. Technically, we were able to use it, but it was not a pleasant experience. I wrote to the host, they promised someone would come the next day but noone came before we ended our 2 nights stay.
