Overall quite good. The store at Madrid Airport in T4 is easy to find. If you land in T4S, be sure to take the shuttle to T4 to find the store. I wandered around T4S for a while... When returning the car, make sure to go slowly. If you drive too fast and miss the entrance, you'll end up at the parking lot's toll booth. Once you're there, you can't go back and will need to take another lap around. The actual car return entrance is a small, inconspicuous opening on the right before the toll booth.

Great car, better than expected. Fast pick-up and drop-off.

Fast and easy booking. Good prices.

I booked an automatic car, but given a manual gear car as they did not have it at this location, I have no choice but to take it.

The car was fine and the staff very helpful. The hire location is close to Plaza Espana in a narrow one way street, currently exacerbated by major building works. It can be challenging to collect and return the vehicle with so little space to manoeuvre - a skip full of rubble was being passed over the car as we were trying to hand it back and the traffic was horribly backed up. If europcar could arrange a separate secure area for pickup and return it would be great.
