Avis is a scam. They lure you in with low prices, but once you arrive, the staff starts increasing the prices with a bad attitude and even threatens you. They have cars available but won't rent them to you unless you pay more to switch cars. Then they add insurance and various extra charges. Terrible service! The staff is even worse, taking advantage of language barriers and our helplessness in a foreign place to make more money. They quote you a price, have you sign a form, and then suddenly the cost is over a hundred euros more. When we tried to cancel, they claimed there were no cars available and refused to serve us. Their attitude was horrible, basically telling us, 'Take it or leave it.' Do not be tempted by their low prices; you will end up paying much more. This ruined our trip and our mood. Unlike in our home country, there is almost no service, and language is a huge barrier, making everything very cumbersome and inefficient. I recommend reading reviews and doing thorough research to avoid our experience. In the end, we couldn't rent a car, our complaints went unanswered, and they charged us for three days. Consider this money spent as a warning to others. Avis, never use it!
