Kitty's son met us right on time to get us the key and show us in, and Kitty checked on us shortly after. The space is basic and clean with a small stove and refrigerator. There is a quad outside that got a little noisy at night, but we were able to sleep fine even with the window open. In order to get into the city center, it's a short walk to the tram stop, and then you can either make one change at the station or do bit of a walk. All told, Kitty is a great host with a good space, and I'd be happy to stay there again if we're lucky enough to visit Berlin again.
