Pretty good.

A very disappointing experience. I already paid for full insurance, but upon arrival at the store, I was presented with three options:
1: Deposit of 2000 euros. If any issue occurs with the vehicle during use, up to 4500 euros may be charged. The deposit will be held for 5 weeks.
2: Deposit of 150 euros. If any issue occurs with the vehicle during use, it's fully covered. The deposit will be held for 7 days. Return the car with a full fuel tank. Cost is 49 euros per day.
3: Zero deposit. If any issue occurs with the vehicle during use, it's fully covered. You can return the car with an empty fuel tank. Cost is 47 euros per day, plus an additional 90 euros.

This is essentially forcing customers to purchase extra insurance.

The rental company offers packages that include toll fees and insurance, which is quite suitable. It saves the trouble of car inspection, and the car provided even has a green zone permit.

The wait time at the airport for car pickup was incredibly long. I had to make five or six calls before getting through, and then waited for a long time before the pickup arrived.

Do not book from this company, it is full of traps — each issue is different. First rental period: July 25, 2024 - August 23, 2024 Second rental period: August 23, 2024 - September 5, 2024 1. During the first rental, the staff informed us that the fee for adding a second driver would be capped at 50 euros, which sounded reasonable. So, we changed our second booking from another rental company to Flex to Go. However, when it came time to add the second driver for the second rental, they said it would cost 13 euros per day, totaling 168 euros for 13 days. Normally, rental companies have a fee cap for second drivers, usually around 60 to 80 euros. This was the first trap. 2. On the very first day of the second rental, the warning light came on, indicating low tire pressure. We checked it at a gas station and found the pressure was fine. On the sixth day, another warning appeared saying the car needed oil and was due for maintenance, with a driving limit of only 300 km remaining. We headed to the nearest Flex to Go location in Nuremberg to exchange the car, which took two hours. Yet, the company did not send us a new contract after the car exchange. After two days of follow-up through Zuzuche (their platform), we received a very perfunctory contract from Flex to Go, which did not include details like scratch information for the vehicle. Luckily, we had documented all scratches with photos and videos. 3. On the fifth day of the second rental, the front desk staff who had originally served us called, accusing us of entering Czechia without paying the cross-border fee. I confirmed that we had not traveled to Czechia, but they insisted we had been “abroad” and charged us 600 euros. The next day, we went to the Nuremberg Flex to Go branch and checked the car's GPS, which showed that the car entered Czechia on June 1, 2024. However, we were not the ones who went there—yet they still held us responsible for it. The front desk's confusion meant that this penalty was actually related to the first rental, not the second. 4. During the first rental, we paid the cross-border fee, but due to the staff's negligence, we were only marked for Zone 1. The countries we visited were also included in Zone 2, which led to a penalty of 600 euros.
