We recently had a limited stay in Madrid. Prior to arriving we contacted Spain Day Tours and requested a private one-day “historical and cultural” tour of the Medieval City Walls of Avila and Segovia. Each is a UNESCO site. Our experience was PERFECT. They tailored a first-class tour for us that exceeded our highest expectations. The cost was reasonable, accommodations and transportation were excellent, and our guide who proved himself to be extremely knowledgeable was amazing. We strongly recommend Spain Day Tours for anyone desiring an informative and memorable tour experience.
