The appartment we booked wasn't available anymore due to a lick. Daniel provided us a replacement, without any reduction.
The place he provided us was smaller and older than the one we booked originally. Some renovations are necessary as the place is quite damaged in some places (bathroom notably).
We did not get any deductions from the original price we paid, however the place was not as good as the one we were supposed to have.
Moreover, the place did not feel really safe, as the main door of our appartment did not close very well.
