The location of this hotel is outstanding. It's on a small canal, and within a very brief walk to St. Marks and the Doge's Palace. The hotel itself is quite old, as you might imagine in Venice, but appears to be kept up pretty well.
The hotel is not easy to find, but the staff did an outstanding job of telling us how to get to the location, including directions from multiple locations, photos, and clear communication in English.
The hotel is not staffed 24/7 -- it appears that the office is open from about 9am to 4:30 or 5 pm. They did give us clear instructions about how to access our room and our key when we arrived late one evening (thanks to some typically Italian transportation problems).
While we were there, unfortunately the main HVAC unit had failed and they were waiting on a technician to repair the system. We had a room in the top floor of the hotel, and it was EXTREMELY warm the first night, even despite having the windows to the canal open and a fan running. (probably 80 F/27 C). Since there was no staff there, we had no way to know what the problem was and assumed we were doing something wrong with the thermostats. We found out the next day about the problem, and the staff worked with us to find us a cooler room on a lower floor. It wasn't ideal, but we understood that repairing a system like that isn't super-easy in Venice, and we were grateful the help to find a more comfortable solution.
Overall, a great location on a canal for a reasonable price.
