Overall service was good, no upselling.

The reserved car was not available when we arrived at the store. We were given two options: a free upgrade to a Mercedes Benz van or a small manual car. On the narrow streets of Spain, driving the Mercedes van was impossible, and with two large suitcases, we couldn't fit our luggage in the manual car. Essentially, we were given two unusable options. After almost 3 hours of back-and-forth communication, they finally agreed to get a car from another location, and our luggage could barely fit. The car we got was a downgrade (a small Kia), but it only cost us 20 euros less. The entire process was extremely frustrating, and if it weren't for our necessary travel plans, I would have canceled the rental right then and there.
