In Barcelona City

All they cared about was us upgrading the car for more money. When we said no, they immediately changed their attitude and became very dismissive.

Not entirely impolite, but the conversation was unpleasant. Diesel cars need to add AdBlue, which is uncommon in China. I didn't know about it, and they should have informed me when I picked up the car to avoid problems later on. I had to contact customer service multiple times, and international calls are expensive! Luckily, I saw the prompt. If I hadn't noticed it, who would have paid for the towing service? I later realized that this thing had to be added continuously. So why not mention it in advance? Tourists from other countries might not be familiar with your car's special requirements! I added AdBlue twice. When I claimed the reimbursement, the counter staff asked me why it was twice. How should I answer that? I could only say that your car prompted me twice! Such unnecessary questions are not needed. I didn't want to add it twice either! Additionally, when charging fees, just charge my credit card in euros. My credit card will handle the conversion. Why convert to dollars? Not only is the exchange rate high, but there are also extra fees!

Excellent service, no pushy insurance sales. After exiting the security gate, proceed straight towards the main airport terminal, you'll find the rental counter on the right-hand corridor. There's a service desk in the parking lot with staff ready to assist with vehicle inspection. The signage in the parking lot is clear, and returning the car to T1 is straightforward by following the car rental signs to Europcar. Vehicle inspection was quick and efficient. This is the best car rental experience I’ve had in years, five stars.

The queue was very slow. The most crucial issue was that the right rear tire burst shortly after I started driving. Although I refueled to full, they claimed it wasn't full and charged me an extra 10 euros.

Went to the wrong terminal because the car rental location details on the website were not clear, but the service staff was very nice and didn't make us go another round trip. However, the navigation system from Europcar was not impressive (even though it had Chinese), as it easily lost signal.
