Richard was a terrific host-- good communications beforehand, and very flexible about an arrival and departure time. The place was clean and spacious-- larger than it seemed in the photos. It's very well located near Schlesisches Tor. I was concerned about noise from the street, but this was unfounded. There was however a late-night party with loud music in an adjacent apartment (on a Sunday night-- only in Berlin!), so I was a bit short on sleep for work the next day, but otherwise this was a great place to stay.
