This place is great - the location is a little off the beaten path, but not hard to manage at all.
one thing to mention: it's certainly in the former eastern berlin...bleak surroundings - but it's no big deal, kind of cool actually.
the hostel itself is great, near a train station, rents bikes - very clean rooms and bathrooms, well, we did have a private...
it also had a little bar, a good looking breakfast, and my favorite - table tennis!
**now, i didn't stay at this place, but we went walking past it in our explorations, and it looked pretty good from the outside, a much better location than pegasus:
