Highly recommend you to not book this or any flat under the CityRelay name. Overall professionalism was mediocre since no email or any call has been answered. The apartment was ok (as shown on the pictures), the locks were e-locks and would open through an app on the phone. One day I came home and could not open the door (the lock malfunctioned), I tried calling the number written on the Airbnb confirmation letter and no one has picked any of my numerous calls (throughout my whole stay). I had also texted the agency through the chat. So far no response. Waited for hours until someone from CityRelay could come in and assess the situation. I was told it malfunctioned and there was not a chance that a locksmith could come and fix the clock (it was 8PM), I offered to contact a 24/7 locksmith myself, which they denied. This happened two times during the two weeks of my stay, and there is absolutely no way to be sure that it won’t happen again.
