The situation of the appartment is really amazing, it can't be more central! (bus, U-Bahn, S-Bahn, trams)
About the appartment itself, some points could make the place absolutely gorgeous, but for now, there are minor disageaments that, combined all together, make it a bit anoying for a long stay :
- the single bed is a pain in the back, because of very bad springer and mattress
- unsharped knives make it difficult to eat anything else than pasta

Despite that, there is some good stuff:
- there is a lot of space, the rooms are big
- there is a balconny which is great (even if the neighboors smoke quite often)
- it's very very (very!) quite
