Just back from 5 days in Berlin and we had a great stay. The studio flat was small, but had everything we needed. The bed is very comfy, the bathroom has everything you need and the kitchen is great for having breakfast before you head out exploring. We didn't get to meet Dagmar as she was away, but her daughter Christine met us and she was lovely. The apartment is located in a very quiet area, but there is lots of great restaurants nearby (I can recommend Mini Pizza). Most of the big attractions are within walking distance. The Schloss Chartottenburg is 1 mile away, but the zoo is about 2 miles away. If you don't want to walk the train station (Stuttgarter Platz) is only a two minute walk from the apartment and you can get a direct train from Shonefeld Airport, which takes about 40 minutes. We also used the S-Bahn to get around the city when we didn't feel like walking. Overall it was a great value apartment and great as a base to explore the city.
