Dear Lisa,
Thank you so much for your message! We really appreciate your interest. Could you please send us an email or fill in the online booking form at our website? (Cannot link to it here, please have a look at our TripAdvisor profile.) It will help us choose the right spot for you. We have many bookings for the upcoming days, but we will try to work something out. The trip takes about four hours, and we go by foot and we take the public transport, too.
Thank you again for contacting us! We can't wait to hear from you and - ultimately - show you around Prague!
All the best,
Jan and Zuzi
