Fantastic apartment in a great location! Public transport was very good with the flat nearby many tram and train lines making it easy to explore Berlin.
Mark was a great host & replied to all messages very quickly. He gave great directions to the apartment/airports.
Would definitely recommend the flat. (The only thing to consider is that the flat is up 7/8 flights of stairs with no lift, if that might be tricky for you.)
Thank you very much, we had a great stay!
