My stay in Berlin was great in no small part thanks to Frank's hospitality. The room I stayed in was clean, easily accessible (right next to a U-Bahn station) and most of all had a unique character I have not seen in many other hotels, hostels, etc. Frank himself was helpful, and made himself available if anything was needed. Despite its location next to a bar and restaurant the room was quiet and I was able to rest undisturbed when I need it. Overall I will seriously consider staying here again on my next visit to Berlin.
