Haji was extremely nice and made exploring more fun with anecdotes and history that only a local could provide. He sat us down to get to know us and vice-versa at the beginning of the tour -- so that he could best tailor what we would see on our exploration. We went to La Sagrada Familia first and finished the tour by exploring Park Guell. He was even kind enough to offer to ride to Las Ramblas with us and show us things we missed the first time we were there, even though it was technically past the allotted tour time. My only suggestions for anyone taking the tour is to make sure you get your tickets to Sagrada Familia in advance, especially if you would like to go to the top of the church. We wasted some time waiting in line when and we could have avoided that if we knew to pre-purchase the tickets and reserve time to go to the top. Overall, it was a good experience.
