Booking online went smoothly, but then you needed to print the voucher to be valid. How do you do that when making reservation on site? Time table was not updated on happytovisits site, so we got there the wrong time. The sightseeing tour started and the guide was on pre prepared tape. Nothing on which side we should look at and very little information overall and to many different languages so you lost it. Sorry but i would not recommend it as sightseeing tour more transportation.
