We stayed in the apartment for a whole week. It was nice, but you feel that people don't live in this apartment, just stay there for a short time - like, there was no washing-up liquid, so in theory you could do the cooking, but then you're unable to clean anything, or no stock of toilet paper. The apartment is quite cold in winter, and it's humid there, so your towels never get dry. There were also some internet issues, but the host really did his best to resolve them.
At the same time, the apartment is spacious and beautiful, the bed is comfortable, it is situated in the very center, so very practical for exploring the town. The host is superfriendly and gives lots of practical recommendations. I would recommend the flat for shorter periods of time, and all these problems probably wouldn't even show up.
