Sonja was incredibly kind and flexible, letting us check in very early because we took an early train into Berlin. She has set the room up really well, with comfy beds for 3 people and a table and seating area to relax. The room is full of plants and is decorated really nicely. Sonja includes all the information you need about Berlin and the surrounding area, and everything was clear. The flat is shared with her but we felt as if we had our own little apartment.
We slept really well, the apartment is high up and the street is super quiet at night. Big windows open onto the street and kept the room cool even in hot weather. The bathroom is very nice with a powerful shower, and all the essentials are provided.
The location was great too, near tram stops and the Ubahn. It takes 30 minutes to walk to Mauerpark, and the area around there is really nice with lots of restaurants, cafes and shops. We were really happy to be so close to the centre of Berlin for a low cost.
