Hey, we (4 girls) stayed in Jonas'appt.begin of October for 4 nights and we enjoyed it a lot, indeed. The appt is very nice, centrally located - a lot is to reach in walking distance and it's clean. Jonas was a very charming and helpful host, giving us a lot recommendations for everything what we've asked for - bars, clubs, restaurants, cultural stuff, etc.
You can't be wrong choosing this!!!
