When we checked in, we were told there was a book with instructions on the flat. When we arrived to the flat, there were no instructions. We didn't know what to do with trash, towels or dishes until after we checked out. The TV remote had no batteries, so we had to buy them ourselves. Even then, the cable was a bit difficult sort out.
Also, given the relatively few hours of darkness (zero on some nights), we were expecting more blackout curtains. no such luck outside the bathroom. The single bed in the second room was also very small. The couch had more space. Wasn't an awful experience and once the kinks worked out, we enjoyed our stay, but it definitely could have been better.
