Check in was very uncomfortable because we had to pick up the keys in the middle of the night far from our apartment. Also, got charged 80 euros for it.
I would suggest to find more innovative ways to unlock the apartment for guests. Like digital code or remotely.
Also, be careful with the lift, we got stuck in it for one hour. It is quite old and not working properly.
Everything else was really good. The location is perfect and the apartment has everything you need and it was clean.
