Fantastic homely experience. Spent three nights here as part of a lads city break, and couldn't be happier. The apartment was spotless upon arrival and had been stocked with everything we would need, including a few beers in the fridge! Ideally two minutes to the underground and a 10-15 minute ride to Alexanderplatz. I would highly recommend Volker's place, and I hope to return at some point in the future.
