Extremely helpful host. The room was very clean with tea, coffee, wifi and satellite TV with 2 or 3 English language channels. It was everything that was advertised. Exclusive use of lavatory and bathroom.
Good area, near the centre , close to U-Bahn and S- Bahn and there is a temporary new line 12 to Deutsche Oper which is not shown on the official maps yet.
There are good cafés , food stores , a nice square just down the road.
All in all a very good stay and exactly as advertised! I would definitely go back there.
