Very good.

The service efficiency is not very high. I arrived on time, but the reserved Golf was unavailable. It took almost 2 hours to transfer a car from another branch. The car was upgraded but was much larger. The branch said they couldn't provide any small automatic cars. Due to my tight schedule, I had to accept it.

Acceptable

The overall service was good, not crowded, and the process was quite fast.

Overall, the communication was smooth. They will try to sell you insurance, but if you tell them you already have full coverage, they won't push further. If communication is difficult, you can use Google Translate. Greek drivers generally drive fast, but staying within your lane should prevent major issues. Remember to stop at red lights when turning right! It's important to understand right of way rules, and always stop at stop signs!! I'm still not completely clear on all the rules, so I observe how others drive, but being cautious is always a good idea. This time, we only stayed around Athens, especially near the coast, where the scenery is beautiful. I highly recommend renting a car. For refueling, check the fuel cap for the required type of fuel. Gas prices vary at different stations, and you can check prices on Google Maps. If you can't figure out self-service, just ask the station staff for help. We used Google Maps for navigation the entire trip, which was very convenient, avoiding toll roads and highways.
