Our stay in the airbnb from marina and alex has been really nice. We could check in a earlier then sceduled because we arrived with an early train. The apartment is very close to the central train station and we could also reach the city center and almost all of the touristic sites by walk. The check-in via keybox worked smooth but there we're other keycards in the flat which didn't work for the doors but only as lightswitch. So far no problem but we didn't know that so we almost locked ourselfes out once later at night - so be aware of that. The apartment was well equiped and had everything we needed for the one week we've been there. To sum it up: Very good experience, we would come there again!
