EVERYTHING! The tour guides were so insightful and pleasant to be with during our tours. They gave us great education on the history of the cities and made sure to give us great local recommendations on things to do and places to eat after the tours. The drivers and the boat captain were also incredibly friendly.
Really it is a great hotel, even as all veneice building looks antic but it's very modern and very clean from inside. Very clean, nice breakfast!! We surely come back.
