My wife and I had a great time on Agustin's tour. He customized it for us by starting and ending it in Bilbao (where we were staying), and by taking us to see not only the Marques de Riscal winery (with the Gehry building), but also the Bodegas Ysios winery (with the Calatrava building). We also had detailed tours of two other wineries, which were both excellent. Agustin was punctual, friendly, knowledgeable, and considerate. We had a lot of fun and learned a lot. We recommend this tour to others.
