We had the pleasure of a tour of both Avila and Segovia with Ernesto - He arrived on time with a large and comfortable van for our group of 6 - He outlined our plans for our all day tour and was flexible if we wanted to make any changes - He is VERY knowledgeable and was well versed in both cities...including a lunch recommendation in Segovia where we all tried the local delicacy...suckling pig! We would highly recommend Ernesto for anyone visiting the Madrid area and specifically for Avila and Segovia.
