The appartment was really nice. It is rather small, but really cosy. It is close to the metro and in a neighbour full with restaurants and bars. Despite of it it was not loud at all (we slept with closed windows). We had change of the number of people and we got one more bed without a problem.
What needs to be approved is the communication - our questions were answered really late or we got false details about check-in. It was also not really clean.
