Hi Bill, you may want to send a PM to Parrot Mom, she reccomends The Continental on the top of La Rambla, around the corner from the Gaudi Church and two blocks from the Market. I don't know what Star Rating they have, but personal experience can be far better than the Start System.
She also has contact details for a trustworthy driver who picks up at the airport, which may be of use to you.
Hope this helps,
Alan & Katrina
