This studio has the best position you can ask for in Kreuzberg (and this, in my opinion, means in the whole Berlin!). From the big windows you have a lovely view of the canal just in front of the house, the street below is very quiet and anyway the double windows block any noise coming from outside.
You have lovely riverside walks & traditional street markets just.. in front of your door, shops just round the corner and Orianienstrasse in a 5 min walk, same as major underground stations.

Apartment is nice and well furnished, the bathroom is more oldish
and could use a renovation, but that's really the worst one can say, since everything works very well... also made good use of the availabe hairdryer!
The bed is in the upper zone and consist only of a small-double-bed sized mattress (it was all right for me, for those in need of a super-comfortable bed this might be an issue). Anyway there's always the couch downstairs.

I used the apartment as a "sleeping place" while visiting Berlin, so i made no use of the kitchen and of all the domestic appliances provided (tv, musicplayer, etc..) but surely they are a noteworthy feature to point out.
Solid wi-fi internet.

Apartment was clean, had no problem whatsoever during my stay, anyway Max was always quick in providing feedback anytime i got in touch with him.
Absolutely recommended!
