Bernd & Katja's apartment is amazing! It is clean, modern, and beautifully furnished. Checking in and out was a breeze and Bern & Katja were always very quick to respond to any queries we had. The location is fantastic, only one block to the U-bahn and S-bahn, local supermarkets, bars, cafes, flea markets, everything!! We would definitely stay there again and highly recommend their place to anyone. Thanks guys! Erin & Dave
