This is a brilliant apartment from which to explore Berlin. It is clean and welcoming and had everything we needed for a comfortable stay, It is in a quiet building so we slept very well. The location is excellent being very close to public transport and shops. The neighbourhood is beautiful and feels very relaxed with lots of great cafes and restaurants. Unfortunately we did not get to meet Alan and Kasia but were left very clear instructions on how to access the apartment. The sofa bed was a little hard but fine for a short stay. We felt we got good value for our money and would stay in the apartment again.
