We went on this tour with Lenka Phillippova as our guide. She has extensive knowledge of the history of Art Nouveau in Prague as well as history in the city. She showed us some amazing sites that we would never have found on our own. Her command of English was excellent. She was passionate about the subject and she graciously shared her time and knowledge with us. We were mesmerized for four hours ! We were lucky to be the only two people in the group so it was a personalized experience. We cannot recommend Insight Tours more highly- registration was easy, confirmation of the guide and meeting place was detailed and helpful. The tour guides are amazing !
