We came to Berlin as a group of six, and Stayed At the Airbnb for 5 days. We recommend this place to anyone and we're very pleased!
there are five large bedrooms, with comfortable beds, closet space and furniture. also the kitchen is very well equiped and the living room is large, with space for everyone to have a nice night instade. wifi is ok. showers were excellent and bathrooms were clean and roomy.
the location is not right in the middle of all the action, but easily reachable at any hour. also possible to talk all the way to many attractions. there are quite a few local bars around that are very atmospheric and fun, so if you want a more chill evening, it is possible.
the host was quick to respond to every need.
I would recommend this place to anyone, and think it is one of the best airbnb I have visited.
