Great appartment in every way! Spacious, modern, cosy. Everything you could possibly need was there. Cos is a great host, fast and good communication and, although the appartment is completely private, at hand when needed.
Tips where to go and where to eat. Everything is available in the neighourhood. It is great to bike through Berlin. We also booked the Alternative Berlin tour, which is highly recommended, lots of information, great guide, lots of fun.
We loved our stay!!
