Nice place to stay in an old building on a quite street 5 mins away by foot from the city center.
Probably a bit small for 4 persons as the second bedroom is quite small, and the living room is not super comfortable for 4 people spending evening there. But still ok for a a short stay.
Staying in winter is a bit of a challenge (but it’s probably everywhere in the region): the heating is made using the air conditioning so if it’s cold outside, you need to run the air conditioning for the whole night in your room. Also there were some issues with the hot water (partly quickly resolved by the host, partly it’s just a bit not stable)
