Pretty good experience. Picking up and exchanging cars was convenient without too much paperwork.

Excellent.

Excess human involvement. The process could be significantly more electronic or simplified. They had to shuffle through keys thrown in a draw for 5-10 minutes before discovering they didn't have the car model ordered so they provided a suitable but very different alternative.

The experience of renting through a rental broker and not directly from a rental company was a little uncomfortable at first (is this transaction legitimate/am I getting ripped off) but in the end the cost saving was worth the third party being involved in the process.

Europcar has different car classes as advertised on easyrentcar. I booked a RAV4 but Europcar would not give me one for the price. They would only give me a Mitsubishi ASX. Had to pay 2x the advertised price for the correct size and class vehicle. Not happy at all. Get this fixed.

Great booking experience, no fuss.
