Dusans flat is great: great location for a tourist, easy to access via your own entrance and really comfy and nice flat. When we arrived our train was 5 hours delayed but Dusan was very flexible and very nice and helped us out with the key without any problems. The flat is on the ground floor with access to the big Danziger Strasse but the curtains block out all the light and we couldn't hear a sound from the street at night so we slept very well. In the area: We had really great brunch at Cafe Tous le Jours which was about 5 min walk south from the flat before we went out on our tours with bikes. Very easy to bike to all the places around in Berlin we wanted to visit. And when we came back in the night we had our nightcap at the small bar Izzy just 50 m from the flat. Really nice and cool Berliner Kneipe with excellent service. I recommend the Mexikaner shot :) Don't forget your vaccination papers, otherwise they won't let you in. So I give Dusan and his flat my best recommendations for a great stay in Berlin.
