The appartement is very light, with high ceilings. The Ikeanese interior has everything you need available (unless you want to make cookies?!). There are some interesting stores in the neighbourhood (don't go to the fake Indian place though) and the supermarket and U- and S-bahn are close by. We haven't met Jana in person, but she arranged everything well and kindly tried to keep in touch during our stay. So much nicer than a more expensive hotelroom. It was really nice to have a home in Berlin for a few days! I definitely recommend.
