The flat is located close to the metro although it is not the nicest area to walk around during the night. Room is big and clean. Bathroom and kitchenette are shared by other guests. The noise level due to other guests within the old building is important, some guests were playing music at 1 am or 8 am and the guests of the room close by were leaving at 5 am making a lot of noise.
Communication was not always effective, I did not have an answer about if I could leave my baggage the last day or how I should leave the keys.
