All I can say, is that when you book as a couple, you run the great potential of being moved to a "sister" hotel, due to unexpected (and unbelievable) "unfortunate water damage" to your previously guaranteed booked room. It was obvious to us that we were being relocated in order to accommodate a larger group, who were to occupy several rooms. The little guy finishes last.
We were denied a chance to visually see the alleged water-damaged room, and had no recourse, but to accept the alternative offered. Who needs to drag luggage around Venice on a Friday afternoon, seeking another hotel?
We specifically selected this hotel due to its proximity to the Alla Laguna San Stae station, hoping not to have to transport luggage for any unnecessarily long distances, since we are both senior citizens.
We were moved to a hotel two water bus stops away, to a less desirable area of Venice, close to the bus station. And during the transfer, the hotel representatives, Davide and his colleague had us enter through the exit portal to enter the boat without paying for the transfer.
Although the room in the sister hotel was rather grand, we needed to get up earlier in order to be moved back to the San Stae station on the morning of our departure, causing us to be deprived of a relaxing breakfast.
Booking this hotel is a gamble.
