Dagmar's place is close to S Bahn Station and you can be very quick wherever you want. The apartment itself is really cozy and well designed. There is equipment for everything you may need and the bed is so comfy. The only issue is that's there is no elevator in the building and it can be a challenge if you travel with a lot of luggages, but of course that's not Dagmar's false. Totally would recommend this place for your stay in Berlin though!
