Maddalena's place is very clean and spacious. The kitchen is fully equiped and has a washer. Maddalena thoughtfully labeled important information in English and made it really easy for us.
The location is convenient. From hbf, bus 142 runs every 20 minutes and stop very close to the apartment. If you can walk a bit, you can also take M8 tram to Pappelplatz or M1 Oranienburger. If you take U-barn, Rosenthaler Platz station is also close-by. Museum Island is walkable.
