Jens' apartment is big and spacious, we were four and had more than enough space. The apartment has two good size bedrooms. It also had a nice living room and dining room to hang out. I would note that the apartment is quite far away from the city center so taking the buses and metro takes a while. Luckily the public transportation seems to work quite well in the city. All in all the apartment was clean but we wish the kitchen ware (water boiler, plates etc) would have been cleaner. Now we ended up eating out but then again had good recommendation on where to eat from Jens.
