Madrid -> Seville -> Valencia -> Barcelona -> Ibiza

Quite satisfied, although my English isn't great.

The procedures were simple and straightforward, no unnecessary talk, just got the paperwork and drove off.

The front desk staff didn't speak much English when I first arrived, which made communication a bit difficult. However, the car pickup experience was excellent. I rented a compact Golf but received a nearly new Volkswagen Tiguan with only 6000 kilometers on it. The car was in top condition, though being a four-wheel drive, it consumed more fuel. Returning the car was simple; I just handed over the keys and there was no deposit fee. They only charged me the rental fee upon return. Overall, aside from the front desk's limited English, everything was great. I would consider renting from AVIS again, even though it's a bit pricey.

Arranged a change in return location through the hotel front desk by calling the rental company. Overall, satisfied. The rented car was brand new with only 9km on the odometer.

Excellent experience, picking up the car at Madrid Airport was quick and convenient.
