Dont Trust booking.com

I am writing this on behalf of my daughter. There was a booking made for her through booking.com for a B&B in Nice, France. If I could upload the pictures she sent me, you would see how BAD this place is!!!. It is absolutely filthy. Dishes/pots/pans left in the dishwasher so long that they have mold on already. On top of that, they want to change accommodation and get the refund but were told they have to stay another night because they only arrived at 11:00pm last night. As they are foreigners this twit thinks he can take advantage of them.. And lets not take away from the really shoddy places booking.com advocates as "decent" accommodation. Absolute disgrace!!!!!!!
