Berlin is always an amazing city and the area of Prenzlauer Berg seems to be today the best balance between a nice cozy and quiet area that is close enough to the centre and to what is always a huge attraction like Alexanderplatz.
But at walking distance from the apartment there is really all that you need, from nice little cafés to good restaurants. And Hendrik leaves in the house all that you need, from the amenities that you expect to a nice info booklet with what is around...a supermarket, some Bio shops and restaurants. In addition to his list I'd suggest also the restaurant Muse for a nice brunch (if weekend) or burgers.
Just a perfect solution for who wants to be in Berlin more like a Berliner and not necessarily in the craziness of the more touristy and crowded areas. And yet, just with a half hour walk, you can be in Alexanderplatz, get on a hop-on hop-off bus to play the tourist on just get on a train and reach any area of the city. Great transportation also from the house with the trams. I strongly suggest to pick this flat if you love to spend your nights in a quiet surrounding and yet reach anywhere you like pretty quickly.
