Easy user-friendly booking system, nice choice of well maintained cars, reasonably priced.

Good cars and a really useful rent a car service. However, it would be convenient to leave the car anywhere, like you can do in other countries. More rent spots should be available

A bit difficult to validate international drivers but customer service does its best to get you across the finishing line. Cheaper than regular car rentals if you are aiming at short term use, like going to the supermarket or visiting a tourist attraction close to a train station on the other side of the country. FLEX solves that "last mile" problem of public transportation. My wife has some mobility issues and FLEX improved our prospects of using public transportation in Luxembourg.

Seamless experience and the help service was very professional in explaining.

You have to return the car at the same station you took it, which might be relevant most days, let's say 4 out of 7 (expressed in days if the week) but definitely not every day.

Terrible expérience ! Overcharged to an incredible amount do to the distance travelled (90% of the price for a normal distance within Luxembourg). Then they charged me €100 ("forgiving" a €250 additional penalty) for FALSE damage that was placed on me a week later. Finally, they take about 2 months to reply to an email.

License validation is such a hassle and customer service is rude and unhelpful

One year later, still not able to log into the app. When I log in, the app opens a web view telling me to download the app. Smart, or not 😭
