Very good.

Not bad overall. The car had a lot of scratches, so be sure to take photos for evidence, or better yet, record a video of the entire car! When returning the car, if you didn’t purchase full insurance directly from Avis, they will inspect the car very carefully. If the staff points out damage and you don't have evidence, it can easily lead to disputes.

The service was quite good.

Despite booking over a week previously so that Avis would have plenty of time to set things up, when we arrived they did not have our car ready (Merc E Class) and did not have anything comparable to offer. After calling their associates, the only available alternatives were a monstrous Merc G Wagon (imagine trying to park that in the land of the Fiat 500) for more money, or a BMW 3 Series Touring. We took the BMW. Then we were informed that the insurance that we'd already paid for via Easyrentcars would not offer adequate cover, and for fully comprehensive cover we had to book with Avis. Given that we'd already had a car damaged in a car park in Italy on a previous trip, we felt that we had no option but to comply with Avis' advice.
