Spacious, light, and charming apartment. Rooms (kitchen, bathroom, bedroom) were larger than we expected. Check-in was smooth and we looked forward to returning each day after sight-seeing and eating our way all over Berlin. Close to both tram (M2 - half a block) and U-Bahn (U2 - 3 blocks). The four flights of steps were a bit daunting for our tired legs, but we'd happily stay here again.
