I had a wonderful lovely stay at Katarina's apartment. It's beautifully decorated & quite compact but with high ceilings and a nice view on the courtyard from the balcony. Also Prenzlauer Berg is my favorite neighborhood in Berlin. The streets are lined with trees and filled with cafés and great restaurants. Katarina is a perfect host, reliable and efficient. The apartment is quiet and private and certain details like the espresso machine & the alcohol fireplace make it cozy and charming.
