Communication and check-in were great. The location is a few kilometers from the centre, but that's easily reachable by metro, or simply by walking for about 40 minutes. The flat in itself is nice, although a bit dark. One thing to keep in mind though, is that if you are 6 people, like we were, the 2 having to sleep on the couch in the hallway won't have the best sleep. That couch is indeed not really suitable for sleeping - very uncomfortable.
