So, to start with the good: the apartment is in an excellent location, with huge windows (so it is very bright) and beautiful view! The hosts were communicating really well, and the host we met for the check in was very friendly and gave us local tips for cool spots to visit / walk to.
You should be aware of two things (that are not the fault of the hosts, but are worth mentioning/emphasising nevertheless): There is no closet, just 3 hangers on the wall. And the building is old, so cigarette smoke from the neighbours can permeate the apartment.
Unfortunately, there were quite a lot of things we did not like: There are wet/mouldy spots on many places around the apartment: the ceiling of the living room / above the shower / above the kitchen cabinets / next to the bed. There is a plug next to the window that is coming out of the wall which is potentially dangerous. The mirror in the bathroom is cracked on the side. And the flush needs 10+ minutes to refill between flushing. Unless these are fixed, I unfortunately cannot recommend this place to anybody.
