We went to jonas apartment for 4 days on a work trip. The place is big and well located. It was a bit messy (the previous one’s bed sheet where drying in one of the rooms) but ok for the price and our use. At night and weekend the other part of the building (an old abandonned telecommunications center) turn into a fashionable night bar. Lots of Berlin beautiful people come here but there is like a bumping vibe until late.
