Avoid, avoid!! Terrible service from the Enterprise office at Bilbao airport. When returning a hire car, the girl behind the counter (Naiara) inspected the car and decided that there was a chip on the windscreen, which was invisible to us. On much, much closer inspection it looks like there may be a tiny mark smaller than a mosquito. She started scratching it with her metal pen and made it several times bigger. Then proceeded to charge us for a brand new windscreen. We took pictures of the mark. A few weeks later when we receive the bill and new pictures of the damage from the repairs garage, they show a completely smashed windscreen!!! And the invoice states broken windscreen. On further investigation it turns out that the repair garage is also located at the airport and probably run by the same company that runs the Enterprise and Atesa franchises in Bilbao airport. We called them multiple times to clarify and they were obstructive and extremelly unhelpful. Enterprise head office should be investigating how these people at Bilbao airport are representing the Enterprise brand and company name. The service that we received was awful, and their behaviour was more suited to backstreet dodgy dealers than to a reputable multinational company. Enterprise should be embarrassed of how this Bilbao airport office is trading under their name.
