Viator tour was great! Friendly guide full of suggestions and tips. Was worth the price when we skipped the line at Sagrada Familia which was stretched around two blocks in the hot sun! We would not have had time to see anything else in Barcelona!
Tour of Gaudi highlights was well-paced and inclusive. Felt we got our moneys worth and then some! Came to Barcelona on our own before joining another 14 day tour of Spain. Viator made sure we saw the must-see sights and saved us time just blundering around on our own.
Only criticism was not being returned to starting point of our tour which was near our hotel. We did walk down Passeig de Gracia about six blocks and viewed another Gaudi masterpiece, Casa Batllo, on the way to our hotel-tired but content. Great guide! Barcelona was our favorite city of our Spanish tour.
