Jang and Christian accepted our request on a very short notice and we had a great time at their place. It's perfectly located. Also, the apartment was really clean and they both provided us with everything we needed. Unfortunately, the walls are very thin which means that you need to be really quiet to not disturb anyone. We couldn't sleep that well because our neighbour snorred loudly and had a phone call in the middle of the night. As this wasn't the hosts fault, we still recommend staying at this place!
