We were two couples and we stayed 5 nights at the apartment. We really enjoyed our stay there. The apartment is very clean, cozy and warm (we have been there during cold weather). The rooms are big and very confortable. The kitchen is fully complete and has everything you need to prepare any kind of meal. The neighbourhood is beautiful, residential and very quiet. The river is only one block away and there is a lovely park on the other side. The S-Bahn and U-Bahn station is just across the street, 25 minutes travel from Brandenburg Gate. The apartment is on the 4th floor and there is no lift. All the time we felt at home, and we would consider this apartment as our first alternative if we had the chance to return to Berlin!
