The comunication with the host was simple and easy. We had a nice stay, but mostly because the apartment is in a great location in the city centre.
The apartment we stayed in wasn't the one we reserved and it wasn't in great shape. The curtains were broken and just rolled behind the TV. There was no cutting knife in the kitchen. The smoke alarm was ringing because its battery was empty. Some of the lights in the apartment didn't work. Also lights at the main staircase of the bullding didn't work so it wasn't pleasant entering or leaving the building during the night.
