Smooth.

Easy pick-up and drop-off process, instructions are simple.

We were given a complimentary upgrade and the car and the process all worked very well. Because I'm AVIS preferred I could skip the incredibly long queue in the main booking hall and go straight to the preferred desk. If I wasn't I think I would have waited over half an hour to get to the front of the queue (which we stood in first before seeing the sign to AVIS preferred)

All worked vey well and when I had a support query it came back quickly with an answer

The car they gave me was different from the one I rented.

The staff were very polite and not overly picky. They didn't push for insurance sales either.

Last three times I have rented with AVIS the car was not cleaned / vacuumed. At first I thought they forgot to do it, but after three rentals in different cities I am beginning to think it's their policy to let cars through the system with apple cores and trash left in them for the next guy.
