I was staying at Konstantin place for almost 3 weeks and everything was great. He has three awesome flatmates, they were really friendly and outgoing, I loved to spent time with them. It's a typical student flat, it provides everything for a ˝decent living¨. At the time I was there they were still sort of moving in, but it didn't bother me at all. Prepare yourself for cca. 80 steps, free workout every day ;)
