Clean and modern but small apartment in a great neighbourhood. Berlin's main touristic sites are at walking distance and public transport is just a block away. The apartment is small (bedroom/kitchen + bathroom) but great for a single person or couple to explore Berlin. The building is next to busy train and S lines so in summer there's is a lot of noise if you sleep with the window open so don't plan to sleep in. Arrangements with Claudia & Steffen were perfect, they responded quickly and everything worked as planned. Maybe a little expensive price/quality wise but would definitely recommend it!
