The apartment looked much better in the pictures than in reality. Also, since we visited in December, the apartment was extremely cold because there is no heating system in the flat and our room had a big window with thin glasses. A little noisy too since it faces a main street. Also we were not aware that other 5 rooms were in the flat for other guests. This made our mornings also very noisy since 10 other people were moving around so we could hear everything and kept on waking up. This can be the fault of the old doors.
The price is very cheap (even considering the additional city tax) but the communication with host was also not the best since he was half an hour late for our check-in (that they proposed).
