We highly recommend the appartment which is in a very quiet neighborhood, it's very spaciaous and clean, has everything to cook in the kitchen and is near a bus station briging you to the S-bahn. The distances in Berlin are huge- something we did not realize coming to Berlin. The use of the public transport is easy, you can have a 1-day or one-week ticket pass with the BVG for all public transportation in zone 1 and 2. We met Kriss, Tobias's wife and had a very nice exchange with her, so you can be assured that they will be attentive at your needs. We loved the appartment and the owners. Thank you for the nice reception with fresh fruits and nice smile !
