Mario was WONDERFUL!! We booked this tour (there were 6 of us), to help us stay awake on our first day in Barcelona and to get a feel for the area and enjoy some tapas! We were concerned about our booking time because we were arriving by air, find our way to our hotel and check-in. Mario was very flexible – I messaged him when we departed our plane and let him know our progress as we made our way to our hotel. He met us at our hotel after we got checked in and off we went on a GREAT walking tour. As promised in his tour description, he took lots of photos of our group as we explored the area and sampled the tapas. When we got home, he sent the photos via email. I would highly recommend Mario!
