I'm curious what people thought about it.
We'll be going to Barcelona after 7 days in Tuscany next year around April (by ourselves) and we noticed that our days and cities align perfectly with this tour (although we'll be an extra day in Barcelona before it when we plan to do the Shadow of the Wind walking tour). Everything in the tour is what we planned to do (except we would also do Montserrat on the first Sunday and we'd have to scrap that).
