We started at one tapas bar where we met our guide and others that booked the tour as well. Our guide was a Barcelona native that you can tell loves her city. She was very friendly, knowledgeable and happy to answer any questions.
But this tour wasn't all about food, we walked through an old church that had burned down and been rebuilt which was ornate and gorgeous. We also passed by a building built atop of Roman ruins that you could see through glass windows into the basement. If we had more time we would have gone back and toured it.
The depth of knowledge was incredible and really let us experience the city before venturing out on our own! We suggest taking this tour on your first day in Barcelona to set yourself up for an amazing trip!
