I highly recommend staying in this apartment if you plan on visiting berlin. The location is incredible -- close to tempelhof park, with coffee shops, little breakfast places, and delicious bibimbap all within walking distance. The apartment is also very close to U Leinestr., which makes traveling around the city quite easy.
The design of the apartment is elegant and simple, with big windows that overlook a nearby park. It is also very clean, and Francois (our host) was easy to get in contact with whenever we had questions.
