Wow! We just finished both a full-day walking tour and a half-day car tour with Robb, and it was one of the highlights of our trip to Europe. Robb planned a customized itinerary around the interests of our teenage daughter, who is very interested in art history. Robb is extremely knowledgeable not only of the history of the city, but also of its art and architecture. He took us to the big sites (Sagrada Familia, Santa Maria del Mar, Park Guell, Picasso museum, etc.), but also to lesser known sites down little alleys and side streets. He had so many stories that even our 10-year old paid attention! He took us to a couple of great restaurants, and a churro bakery that was so good we went back on our own later to buy more. The pace was very enjoyable — not too fast, not too slow, and we felt free to stop and do a little shopping along the way without feeling like we were falling behind schedule. I highly, HIGHLY recommend Robb to anyone looking for a great personal tour of Barcelona.
