My husband and I stayed here for four nights in September and were very pleased with our choice. We will definitely stay here again next time we are in Venice. This hotel is small (six rooms), quiet, clean, relatively inexpensive, and best of all, it's in a non-touristy neighborhood. The rooms are not spacious or fancy, but they have character, as does the proprietor. This woman speaks only Italian, but she is friendly and helpful and communication was not a problem. When she explained to us how to use the TV and A/C, even with our very limited Italian language skills, we understood. She kindly allowed us to leave our bags the day we checked out so we could spend our last hours in Venice sightseeing unencumbered.
By the way, there is a room tax that must be paid before you check out. Don't panic and think you are being asked to pay for the room again, as we did! It's about 2 euros per person per day.
The towels were a little rough and the pillows could've been softer, but we were plenty comfortable and slept well here. Earplugs might be in order for those who prefer leaving the windows open to using the A/C, as sounds are amplified by the narrow street, and late-night revelers can be noisy passing by below. We didn't eat breakfast on the premises due to what others here said about it, but found a very nice cafe over the bridge and a couple blocks down, at the intersection of Rio Terra Farsetti and Rio Terra S. Leonardo.
Alloggi Sardegna is a wonderful place to stay to escape the hordes of tourists and see regular Venetians going about their business. I look forward to staying there again.
