Ulla is great host! She is always available with prompt and detailed answers. And her friend Andreas is even more kind: he welcomed us in advance and he provided us all the necessary instructions for a great stay. He also gave us some suggestions about garbage in the following days 😉.
The apartment is fantastic. It is modernly furnished with great style, very clean and functional: it is perfect for 2 or 3 families, there are many bedrooms and one very large and cozy reception room where you can have breakfast or dinner all together. All the services (WiFi, digital TV, washing machine, dryer, dishwasher, etc) are brand new and workings very well. Also the location is very good: in a residential and quiet area of Berlin but close to the city center that can be reached easily with trams or tube.
An highly recommend apartment in Berlin.
