Worst transportation service I have ever used. Made me late even though I had an appointment pickup time. Don't bother.
I highly recommend A Friendly Cab. I had a ride with one of the owners of the company after I left the hospital in Flagstaff and he was really friendly and helpful. He gave advise on taking the shortest route and he even went searching for my phone at the place of my accident which was only on the route back for him. He actually found it under a bush and sent it back to my home in the Netherlands! It shows that there are still good and honest people in this world!
