I strongly advise you don't use this company in Malaga. I had over 200 Euros extras added to my bill without any discussion or my agreement. In the small print, in Spanish!
It's called fraud.
Worst car rental in 35 years.
It's bad enough to get hassled at car rental pick ups to add extras you don't want and definitely don't need but normally it stops after making it politely clear you are not interested.
So smuggle it in your contract is on a totally different level.
So be warned. If you have already booked check your contract very very carefully. If you can, book with a different company.
Definitely NOT RECOMMENDING THIS COMPANY
