I offer a beautiful, little flat in a very central place in Berlin. Its very close to U2 Eberswalder Straße. It has a kitchen and a bathroom. It is good for a single person or for a couple, since the bed-space is large enough for two. There also is a sofa that you can expand to bedding, but it is old, and not very comfortable for sleeping, but if you are 3 people it could do.
The bed is actually two mattresses in a bed space (see in foto), so if you are no couple, you can throw down one mattress, and use it to make yourself a seperate bed on the floor.
