Elena's cozy place is easy to get to in Prenzlauer Berg and isn't far from the M10 Tram and the Eberswalder Straße U2 U-Bahn stop. The M1 and M2 Trams are a little further away, but not much. It's easy to access Berlin using public transit from her place.
There's plenty of restaurants, cafes, bakeries, shops, small bars and other places to explore giving that it's in Prenzlauer Berg.
There are also two grocery stores not far away.
There is drop-off laundry service called the Laundry Room that is nearby.
Everything was fine with the apartment and as expected.
Communication was ok.
I'd stay there again.
