My family and I (6 people) stayed here for 4 nights and it felt like home away from home. The place looks exactly like it is in the pictures and it's clean and spacious. There's a 5 minute walk to the nearest metro station and be sure to get a few chocolate churros on your way there at Xurreria Berlin.
Eitan was super responsive and the guy that welcomed us in and returned our luggage before leaving for the airport was always on time! (we still had time for exploring before going to the airport so we left our luggage for safe keeping with Eitan's team).
