Great tour and nice pace - Our tour guide. Sebastian was a young man that was local and told us everything true and some not! He was a great guide and we had a very nice pace and information.

Do this first! - Would absolutely recommend starting your Prague trip with this tour. Ella was an excellent guide, sharing useful information from political history to her favourite places to eat, drink and suggestions for unique souvenirs. We spent just over 2 hours walking with Ella, and learned so much new information and noticing more despite exploring Prague ourselves in the days prior. The group size is kept small which is great for asking questions and hearing the guide. Ella was a brilliant guide, so friendly, funny and informative- her English is excellent. Thank you for a lovely end to our Prague trip!

Michal was great! - We highly recommend this tour, which we took with a terrific guide, Michal. He was extremely knowledgeable, friendly, helpful, warm and humorous. If you book this tour, you won’t regret your choice and you just might get lucky enough to have Michal as your guide.

A guided tour of Prague! - Our guide in Prague, George, was friendly, knowledgeable and passionate about the history and culture of the city from the very beginning. With each brief stop, he brought the place to life with facts you wouldn't find in your average travel guide. George gave great local tips for food, hidden gems and places to explore after the tour. If you're visiting Prague, we highly recommend you do a "Get your guide" tour, and hopefully with George as your guide – he really made our trip unforgettable!

Effectively two separate tours - Adam, our guide, was great around the Old Town. He was very knowledgeable and engaging. We hadn't appreciated that the Astronomical Clock & Underground Tour was a separate part conducted by one of the official town hall guides but it was fine. We had also hoped to hear a little more about how the clock actually worked.
