Thorough greeting and briefing at check-in from Ute - backed up by a glossy ring binder including restaurant and shop recommendations as well as less touristy places to visit. There were even Berlin and transportation maps, which were invaluable.
We appreciated a fan that got us through the surprisingly hot, June nights. (We Americans are continually caught out by lack of European AC in AirBnBs.)
Full length windows really open up the rooms, adequately covered by good curtaining. Great shower and utilities.
Excellent location. 10 minutes walk to Berlin Wall and even closer to restaurants, and groceries. Five minutes to the nearest station. Very quiet at night.
Note. BVG app on your phone is essential for navigating the initially confusing Berlin transport system.
