Overall our stay was okay, but personally I wouldn't stay again because of noises around the flat. On the ground floor is a bar. You can hear music all night especially at the weekend. The flat is badly soundproofed. We heard a noisy conflict in flat 1 at midnight. One day after somebody was even ringing at our door at 01:30 a.m. Moreover there was mould in the shower.
Check-in and check-out have worked without any problems. Bed and towels were clean. The flat is cosily arranged.
