Excellent apartment for exploring Berlin. It's located close to the tram and a 10 minute walk from the S and U Bahn station at Schönhauser Aller. Communication with Ellen was good. The apartment was spotlessly clean and all the beds were comfortable. The only slight negative would be the kitchen which is very small. Had we tried to cook a proper meal, we'd have struggled - for example, the oven shelves were missing. On the whole a very enjoyable stay. Thanks!
