I think you are not fair to us and/or misunderstand why I had suggest you my other flat:
1/ I didn't rent the flat you booked to somebody else and as explained, you could have stay in the flat you originally booked, but (see point 2/)
2/ The flat (le Loft Victoria) on top of the flat you originally booked (La Suite Victoria) was booked by a group of students who traveled to Nancy for Birthday party. As result, la Suite Victoria stay unoccupied because I don't want you (or anybody else) to complain about noise/trouble
Knowing you had a little baby, I had proposed you to switch for a bigger/better and a more quiet flat, and as far I remember, you had agreed on it when I explained you the situation on arrival.
So I am very surprised about your negative comments, especially you had booked for 2 adults and 1 baby, but you arrive 3 adults and 1 baby forcing us to arrange an extra-room on spot.
Anyway, I hope you had a good stay in our nice city and wish you a good trip.
