The apartment is very close to the famous Mauerpark (5 min walk)
Also 5 min walk is the station called Schönhauserallee, a key station for public transport that gets you anywhere in Berlin.
There are a few supermarkets, Spätis (tiny supermarkets that are open till very late) a shopping mall, sweet bookshops, cafés and restaurants from all over the world (e.g. best humus in town is just next door)
You will share the flat with 2 great guys who will always help you out if needed :)
