The apartment is in a great location and looks nice. Sufficient space for 4 people. As previous visitors have stated, it can get noisy because of thin walls. It was calm in the night, though, and not a big problem. The sleeping couch was noisy and uncomfortable to sleep and sit in. There was also a noise in the walls that kept coming, and persisted even when the AC was off. We also discovered multiple hair strands and some brown stains on the duvet cover when we arrived.
Cedric answers quickly in the chat and the self check-in/out worked great. The AC also works fine.
