The flat in the pictures was different from the one we stayed in. While the main area of the flat is pretty much the same as in the pictures, the bathroom is quite different - there is no window, it is quite dark, there is mold, the shower head must be kept in a hand as the shower head holder on the wall is broken. Also, I wanted to use the hairdryer but when I removed it from the shelf I got to know that the handle is broken so I never used it.
The check-in is from 3 PM, so I would not complain about not being able to check-in before that but I was told I can do it and leave my bags at the flat at 12:30 PM. When we got to the flat at 12:30 PM no one opened the doors, so we came back to the flat after 3 PM.
I just wish there was better communication and that the flat listing images would show the flat that we are actually staying in as the bathroom was dissapointing.
