We enjoyed our stay very much at Felix's place. Beds were very comfortable and quiet. Very close to U-Bahn station so you can easily get anywhere in Berlin by public transportation. Also, a nice bakery nearby, for breakfast, a grocery store and a few nice restaurants in case you don't want to hop on public transportation every night. Felix was very accommodating meeting us after hours to check in, with a smile, and really seemed to care that our trip went well. If you are looking for a place to stay in this area rest assured that this is a great place to stay.
