claudio was very kindly and helpful.
the room was exactly like in the description and clean.
you are not able to lock it from inside (just with a lock from outside the room) that was the only bad thing about it.
i didn't receive an exactly address of the apartment but claudio will change it. that was a little bit unpleasant after having a long day in the city and arriving late but we could handle it in the end :)
altogether we were satisfied.
