We had a great time staying at Natalie’s flat. The place was spotless, there were thoughtful touches (like candy and chocolate left for us) and Natalie was very helpful sorting out our check in when we were significantly delayed. She has lots of great guides and recommendations for what to see and do in Berlin, and the location was excellent, in great proximity to restaurants, bakeries, pubs, a laundromat, and an S-Bahn station. We felt very safe and comfortable and would be more than pleased to return.
