We went on a guided tour, Highlights of Barcelona. Our tour guide was a bit weak, she tended to ramble and was very soft but Barcelona made up for it. It did seem a bit lopsided...we spent nearly an hour in the Cathedral but only walked outside Guadi's church (which to be fare, was noted in the program). The afternoon was spent on our own in the gothic quarter which had some lovely shopping. It was a great introduction to a beautiful city.
