Very nice and clean flat! The place is close to the u-bahn stop, so you can arrive in Alexanderplatz in less than 10 minutes. The zone is very quite, and you can find supermarket, pharmacy, pubs...whatever you want.
Sven was very kind with me and with my friend, he is a very nice and helpful person. Easy check-in and check-out!!
If I return to Berlin sure I would stay here again!!!!!!
