Werner's flat is perfect for a large group - I stayed there with my husband, my parents and my sister with her partner and two small kids. The flat has three completely separate bedrooms, all with proper double beds, and one of them has a pull-out couch too. The kitchen is very well equipped, perfect if you prefer to make breakfast or cook dinner in the flat rather than going out. The location is great too, lots of nice cafes close by, and super markets as well - and it's well connected by public transport. Werner is super responsive, and great to deal with - there were no issues at all. A great place to stay in Berlin!
