My partner and I stayed here on recommendation of a friend who had a great experience. We are frequent visitors to Venice and found the hotel and the staff to be quite lovely and nice. The room we had booked was priced well for the area and the time of year. We had a pre-paid double superior which was very comfortable and had a nice clean bathroom with a shower. The room had a wonderful beamed ceiling and a stone floor which is preferred over a carpeted one. The bed was comfortable and the view out the window was a wall and a small street below which is the entrance to the hotel - very quiet which was great. The breakfasts were for the 3 star hotel: coffee/tea, croissants, rolls, yogurt, jams, sliced pound cake etc. The service was professional and with a smile. The staff seemed genuinely willing to assist with any help.
Previous posters have indicated concern over payments. Note, these small hotels get charged a huge amount of service fees for credit card use - so paying in cash is preferred. We noticed a sign saying the POS system was down for local charges (internet, minibar etc). My preference is to pay cash for hotel services so this was not an issue for us. But note that there is a 2 Euro Venice Hotel tax per person per room which is not part of any pre-paid charge.
The hotel only has 8 rooms and is situated in a quiet residential non-touristy area of the city. Ultra convenient for visitors heading to/from Marco Polo Airport via the Alilaguna blue line which stops at the Fondamenta Novo which is much closer than the Ca'Doro vaporetto stop (only 2.5 small bridges to cross).
One note to know: Some visitors may notice a rather odd smell in the bathroom. It's nothing to worry about. Many old buildings & hotels in Venice have old pipes and certain smells may come up through the pipes. Simply closing the sink will alleviate the smell. This has nothing to so with the hotel - common in Venice.
Would stay here again on a return visit.
