Excellent service, both picking up and returning the car were very convenient.

It's okay.

The rental company's staff had low English proficiency. It is unclear whether they deliberately deceived or if it was an honest mistake. We clearly stated that we only wanted to add GPS and no other extra insurance, but ended up being overcharged by nearly 200 euros. On the day of the rental, we repeatedly confirmed with the staff that the total cost was around 260 euros, but my credit card was charged over 470 euros. I believe the business practices of this rental company are very problematic. I advise others planning to visit Germany not to rent a car from this company.

After a small assessment, I was given an electro auto which was horrible and I needed to change after less than 24 hours. With the temperature in Frankfurt the battery does not last and the provided plug in the car for charging was a home one. It would have needed like 30 hrs for charging.

We weren't told where to drop off the car so assumed it was where we had picked it up from. However when we got there we were told we should have seen a big sign telling us where to drop it off but we hadn't seen it. It also wasn't very clear as to what fuel the car took, there was no indication on the fuel cap and it wasn't obvious on the paperwork.
