Ruben was an excellent guide. He arrived exactly on time at the agreed meeting point. He was extremely friendly, helpful, and informative. We learned a lot about the history and way of life in Cuba in addition to the Cannon Shot Ceremony. We would highly recommend Ruben as a guide to anyone who wants to learn about and attend this historical and traditional ceremony while in Cuba. Also, Tour Republic is an extremely efficient company to use when booking any activities in Cuba and would highly recommend its services.
