If you are looking for simple shelter with uncool home stuff you may go for it. The host is dealing with plenty of apartment so it will not a real Airbnb experience for you. He is acting like landlord, try to give you as minimum as possible (For instance I asked only one favor from him but he simply declined, not even show flexibility). So you need to negotiate everything upfront.
Positive point; good location, silent and well heated apartment.
Negative points; building is old (apartment hall smells most of the time), apartment roughly renovated and cleaned, weak amenities( we needed to ask for new pot/pan etc), bed is too hard to sleep and make noises when you move, sofa in the living room is dirty and about to crack.
