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.

Excellent service

Make sure to navigate to Parking Rent Car T1

First class service, one minor 'challenge' at the time of collecting the vehicle but the counter staff worked very hard to resolve the situation to my satisfaction.

Very pleased with the service provided by Easyrentcars.com; will definitely use this service again

Closed when we arrived. Other staff very pleasant and helpful while we waited. Then the Kerry by Europcar staff member was helpful but drunk when serving us.
