Nikolai has been one of the best hosts I have had so far. He makes you feel right at home as soon as you enter the apartment. In the evening he offered us wine and in the morning he made us fresh coffee with his Italian espresso machine.
From the apartment it is just a 2min walk to the tram station which will take you to Alexanderplatz or to Eberswalder Straße (Bars and Cafés, Mauerpark) in under 10min. Overall an exceptional stay!
