Just back from Prague- here is the site for the shuttle service that I took the trip advisor recommendation on. They were prompt, efficient, and helpful! No surprises, flat fee. http://www.prague-airport-shuttle.com/ Drivers both spoke English, and were very informative. Offered restaurant and touring tips, even safety precautions to take. Couldn't have been nicer. Sent an email confirmation with photo and specific directions at airport- reassuring in a new city one is traveling to.
