Does anyone have a recommendation for a company that offers private tours of Barcelona?

You can heck out:
Hi!This is Barcelona (http://hithisisbarcelona.com), Movin'Barcelona (movin-barcelona.com)
Sandra Trours (www.barcelonasandratours.com)

Robert have you personally used any of these.

recdenver - have you been to Barcelona yet and did you use any of these.Thanks. Happy travels!!!!

Yes, I'm familiar with all three.

Thanks!

Robert2533, being familiar is quite different from "having used the services of these guides."
Please cite specifics.

If you chose to do an inexpensive group walk instead I enjoyed the Gotic walk from the Barcelona tourist office which started at their office near Placa Sant Jame. It was 2 hrs long and 12E/pp. They have a number of different themed walks each day from various offices. You can get more info at http://www.barcelonaturisme.com/

In 2008 we used BCN Tours for a day-long walking tour and were very happy with the guide and the whole experience.

The ladies at Foreverbarcelona are great! Try booking Marta, if you can: she's the owner and a terrific tour guide. Miriam was also wonderful and she had wonderful recommendations for the rest of our trip.

Marta is a personal friend of ours. And yes, she´s great and has an interesting blog.
