Absolutely wonderful experience with Sillas as the guide. He was knowledgeable, funny, engaging and courteous. Sillas's command of historical fact, fictions and curious oddities enriched the tour well past my expectations. Tour itself was packed for a one day experience…I had a great time being able to see so many places! Excellent value for price point, no waiting in line (even got in early to the church before it officially opened), small touches like complimentary bottled water. Tour bus modern, safe, climate controlled and well appointed. It also had WiFi, which was very helpful for coordinating plans with my friend for dinner. Pickup and dropoff seamless, good comms from operator.
