Dirk's place was a great space, super clean and very close to public transportation. You are a 4 min. walk to the nearest U-Bahn station, and there's a tram and bus right outside the building. The apartment is near a great shopping/eating street and so eat/shop to your heart's content! Another cool thing about the apartment is that it's next to the Berlin Wall's documentation center. Spend some time reading through the different outdoor plaques and see the area where the wall originally stood (marked by metal spokes and some of the original wall is still there). Dirk was helpful and around to answer any questions. If you are a light sleeper, just bring earplugs as the bedroom is by a busy street. Bed was comfy and the room/bathroom had all the essentials you need to have a good night's rest after your long day of sightseeing.
