Fabulous communication! I booked for my husband who was already in town but extended his stay and had to check out of his hotel. Florian was very responsive and helpful with arranging for key pick up and allowing my husband to drop his luggage off early if necessary. His place was clean, had all the necessities and the price for location was fantastic. Easy, close access to the S-bahn as well as parks, markets and restaurants. We would definitely stay here again!
