Overall, it was ok.
I was in contact with different persons from the agency during the week-end, kind of losing who is who...
The sofa-bad is broken, I had to sleep on the floor the first night. And the other mattresses are not comfortable, my friends felt the springs every night (they still slept, but with backpain in the morning).
There is no living room as a proper space for relaxing and talking. Five people are too much for the flat, you'd better spend the time outside.
All the equipment is working, sheets and towels washed and the place is really clean.
The location is great, but quite noisy (neighbors, other flats on the floor so people at any time can come and go, street noise, etc.)
To sum up, it is cheap, and the quality goes along.
