We highly recommend staying at Remy and Waldo's AirBnb in Friedrichshain. It is located in a fun, hip, and safe neighborhood, with great restaurants and bars, a 10 minute walk to two S and U-Bahn stations, and easy access to all parts of Berlin. Remy and Waldo were such great hosts and were responsive immediately to all our needs and questions. The apartment is very modern and comfortable, with everything you need for your stay. Make sure you check out their recommendations for restaurants in the neighborhood. If you like to get around by bike, there is a bike rental place right down the street. We look forward to visiting again!
