Ulrich was a great host and the flat is very comfortable and spacious. There is an amazing window in the room that opens up and lets in so much air and light. Ulrich and I didn’t have many interactions because I was always out and about (the U-Bahn is literally one block away, winning! Also there is a shopping area close by at Wittenbergplatz) but he is very friendly and respectful of his guests. I definitely recommend his space!
