My husband and I booked the Freetour.com Gaudi, Sagrada Familia and Modernism tour in Barcelona by Barkeno Tours. Our guide Marabella was very knowledgeable and informative as well as funny. We met promptly at the meetup point, rented our headset for $1 euro and started our walking tour. We saw many of Gaudi’s works of architecture and took the metro to see the Sagrada Familia. We enjoyed a lovely 21/2 tour and highly recommend
