The apartment was stunning, relatively small but with everything you might need! The bathroom is very big, super clean, and the bed is very comfortable even if it's "on the floor".
You'll have a night shop conveniently placed within 20 meters of the apartment (they have the best drinks, just try them all). Apart from that, be aware it's a 5 km hike. You'll find a café where you can smoke (hidden gem) if you enter the living block area to your right. A must do for an evening of drinks or cocktails!
Pita shawarma at 100 m to your left. I would sell both my legs for pick axes, just to climb horizontally towards the one pita place that can readily have one other limb, just so I'm not completely helpless helping myself to that delicious goodness. We had 3 in 2 days time (take red sauce and white yoghurt-like sauce!)
Kreuzberg marks the spot for the most laid back community of people I have encountered as of yet. Food and drinks are quite cheap, and if you don't stumble onto something nice, I'll lend you my eyes as well.
Just to shoot myself in both feet to finish it off: it's worth your while (forever booked from now on) and, to be able to have a smoke on the West-side, peerding over the river into the depths of a century of history on the East, is the best Sunday morning coffee you'll have (there's a closed gate, but you can open it, just don't leave a mess and respect neighbours etc)
Last but not least, if you're a coffee-addict like me, try the Cortado coffee pods you can find in the apartment. They are so delicious - and I can tell you as an Italian - that you'll never be able to go back to normal coffee!!
