Ulla is a most welcoming and helpful host. For people like myself with a poor command of the German language, she speaks perfect English. She has a lovely and unusual split-level top-floor apartment in the area of Berlin-Spandau. It’s very clean and cozy. The bedroom is likewise clean, and the bed is very comfortable. I stayed in mid-Winter, and it was always warm. Although the apartment is not in the city centre, all parts of the city are very easy to reach via bus, subway (U-Bahn) or train (S-Bahn). There are regular buses that run along the street outside that connect to the nearby stations. Spandau itself is a very nice part of town (do check out the wonderful Christmas Market if you visit in December), and there are also lovely walks in the nearby forest, should you desire a break from the city.
Oh, and if that’s not enough... Ulla has this incredibly friendly and adorable cat!
