The service was quite good.

Vehicle itself was clean and counter staff helpful but the car was not full (closer to 90%) and it also had only a 2% charge. As a hybrid, I'd expect better. Due to the small gas capacity, we were suddenly on empty during our initial journey.

The car rental company is pretty good, but they charged me a deposit that hasn't been refunded yet.

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.
