Everyone told us to visit Kreuzberg while we were in Berlin so we figured we’d stay in it while we were here for a week and we’re sure glad we did! It’s quiet enough to get a good night’s sleep but close enough so that there’s probably months or years’ worth of restaurants and bars for you to try out. Very close to Mitte if you’re here for work and have meetings to go to there and direct bus back and forth to the main train station was super key (M41). Highly recommended for a week’s stay!
