I called to book a cab about 40 minutes in advance - not giving them very much time. But the cab still arrived promptly and was in fact waiting for us when we got downstairs! The driver got out, opened the doors for us and helped us get our luggage in the trunk. The inside of the cab was clean and smelled nice. And I loved that it was a Prius.
My only issue was with the customer survey discount. I completed a quick survey and got a coupon code for $5 off. We presented it to him at the end of the ride and you would've thought it was the first time he had ever seen such a thing! I don't think he understood what it was at first. It took about 5 minutes while we awkwardly idled in front of the airport, but we got it figured out and received our $5 off.
Overall - an $11 ride that was prompt and clean. I would still use them again!
