Christian was not here when I arrived, but he asked one of his friends to open the door for me and give me the keys. Then, my whole stay was very nice. Christian is very friendly and we had opportunities to talk about his several trips and experiences abroad. The kitchen has a lot of devices which offer a lot of possibilities to cook. The room is bright and comfy. The apartment is close to a lot of shops; S-Bahn and U-Bahn are easily accessible as well. And even though the railway goes just at the bottom of the building, it is not annoying (you can hear trains but it's not too loud at all). Maybe one more thing, one should be aware that the flat is at the 4th floor without any lift!
