Here's what happened: Called Sunday (2/10/13) for early Monday pickup. Scheduled pickup for 4:45 am. Cab did not appear so called the number at 4:55, straight to voicemail. Left voicemail asking what had happened. Roused spouse for ride to airport. No returned call or explanation of why pickup was missed. Have not had time to call again myself to find out what happened, but did have time to write this review. The guy sounds nice enough, but beware!
UPDATE, 5/31/13:
Changed from 1 to 2 stars. Confirmed with Sheila that pickup was indeed missed on morning of 2/11/13. However we did just talk and Sheila was very apologetic and offered a free ride. Clearly these are business owners that do care about their customers and this is worth a lot!
