The apartment was quite nice, it is more or less identical to the pictures and it appears to be quite new. It was also very clean and spacious for two people, but it has a quite poor soundproofing especially regarding noise from the stairwell.
The only thing that bothered me was that the host after our departure claimed that we had one more person additional in our group which was absolutely not the case, yet he accused us. He claimed that his parents living in the ground-floor heard us with this additional person but don't have proof that it was us as there are several apartments. Hence I thought it to be wrong to falsely accuse us.
