I've visited Berlin a number of times now and this has to be the best location of all the places I've stayed. Björn's place is wonderfully peaceful while being in a perfect location to enjoy one of the top neighborhoods for food and culture. And very convenient to trams and U2 line means easy connection to Mitte and everywhere else in Berlin. It feels like a diamond in the rough - a great, comfortable place to come back to after a long day of walking the city (or night of dancing). Björn was very responsive and helpful and if I ever need 2 bedrooms when I come back to Berlin, I know exactly where I'll be staying!
