Good

Chosen car size not available, offer a minibus! As only luxury cars available and they wanted me to pay more or wait an hour. Argued it out and they found me a car. Staff were very nice, but I was late for my meetings as a result of messing about with waiting for the car.

No problem with age limit I encountered with other companies

Have a good cross section of quotes

Fast and efficient

Like: Everything worked.
Dislike: No manual with car. Not obvious that Firefly was part of Hertz. Left so,etching in the car and although contacting Hertz three times no one seemed interested and have heard nothing back. No one returned my call.

Like: We got a better car than anticipated (5 door rather than 3). The lady serving us was very friendly. Just a bit confusing how it's in a corner of Hertz - not everyone would realise that's where you pick up from. They were very understanding about us picking up the car late.
Dislike: Couldn't get through on the phone for quite a while, which was stressful as we were worried we'd be charged for a late pick-up. When I rang Easy Rent Cars they were extremely unhelpful and just said to contact Firefly.
