On the positive side, check-in process, communication with Stefan and the cleanness of the apartment. On the negative side: too loud (during my stay the apartments in the buildings were renovated, the noise was there starting 6-30 am, incl. Saturday), the apartment is too small (aka student apartment to come in and sleep and leave it as soon as you are awake). Washing machine is not in the apartment, you need to go to basement and share the washing machine with the entire building. And lots of other annoying details were not my best friends.
Hotel or this stay? Rather the hotel, I would say despite the positive aspects
