The check-in is not made at the house but at the agency. This is communicated a couple of days before the apartment. We had problems to enter the apartment, none took us to the flat and none told us that the door lock doesn't work properly. Moreover, we had to call again to get the WiFi password because it wasn't shown at the apartment. Lastly, shampoo and toilet paper were not properly provided. Anyway, while the service can be improved, the flat is really well positioned and really comfortable
