When we arrived at the apartment they asked us to pay more (around 6€) just because a weird law. They didn't tell us that info in advance, they also didn't give us any receipt of this payment. The check-in was supposed to do at 15:00, but when we arrived at their office they told us that the cleaning was not finished and we had to wait half an hour more. The worst thing that they asked us to call them when we arrived at the apartment and the cleaning lady who was there didn't speak any English, so it was impossible to communicate with her.
