I recommend Jens apartment, the place is exactly as seen in the photos.
It's located in a quiet neighborhood with lots of good restaurants and coffee houses. The building is very quiet. Checking in was very easy and the communication with the host was quick and simple.
There are four rooms:
1. Bedroom with wide bed (two person can easily get a good night sleep) and shades that make the room dark during daylight.
2. Living room with a photon, big and comfy sofa and a TV. This room gets really sunny early in the morning and there are no shades so bring your blindfold.
3. A well equipped kitchen with a small balcony facing the back of the building, really nice to drink your coffee while sitting out in fresh air.
4. A large and nicely decorated bathroom.
The apartment is on the fourth floor with no elevator.
