The reserved Galaxy model was not available, and the offered Smax didn't have enough space for six people. We had to consider upgrading to a Ford Tourneo by paying an extra fee. Initially, we were told verbally that it would cost about 13 euros per day extra. After agreeing to the upgrade, I had to go see the actual car myself, which was a hassle since the Tourneo isn't available in our country, so I didn't know what to expect. After agreeing to the upgrade, the paperwork showed an additional 16 euros per day, plus a 23.5% service fee and a 19% tax, which amounted to almost 25 euros per day extra. I felt somewhat cheated but had to accept due to time constraints. Additionally, regarding the toll fees for Austria and Switzerland, I was charged 25 euros. Upon reaching the border, I cautiously asked the gas station staff, and they didn't recognize the bill I had. I ended up having to buy toll fees separately for over 40 euros. Upon returning the car at the end of our trip, I asked the Hertz counter and was told that the CROSS BORDER FEE was for taking the car across borders, and toll fees still needed to be paid separately by me. Due to time constraints, I couldn't argue further. This wasn't just a money issue; if I hadn't been cautious and asked at the border, I might have faced fines or legal issues for not having the required toll stickers on the car windshield.

Pickup and return were very convenient. It took a while to find a place to refuel at the airport, but everything else was great.

When we returned the car, we noticed the fuel tank wasn't full. The staff told us there was a gas station very close to the exit, and it was also very convenient to return the car under Terminal 2.

Booked an automatic BMW sedan for 400+ euros, they insisted it was unavailable and gave me a terrible Ford car, a manual without navigation. Then they offered a tiny Citroen automatic also without navigation. I had no choice but to switch to a Mercedes C180 which cost an additional 30 euros per day. After ten days, they charged another 100+ euros saying it was tax. In the end, I spent over 800 euros. What a rip-off!

It went smoothly.
