The unit was great, exactly as described. we didn't spend much time there since we were exploring Venice but we were comfortable while there. It was very quiet at night with a comfortable bed (we only used the large bed in the larger room so can't comment on the others). The pillows were comfy too.
The unit probably could have been a little cleaner but it was still pretty good, and the lady doing the cleaning was a bit rushed by us since we showed up early. So overall, not a significant concern.
Paolo mentioned in his welcome note that there's a great street market just down the road on Tuesdays and Saturdays (go left when leaving the villa). Very cool, with a ton of stalls selling lots of clothes, leather goods and other products, plus a few stalls of fresh fruits and veggies (mostly at the far end). It looked like there were some good prices. Definitely worth checking it out if you're in town on the right days.
Once we figured out how to buy the bus tickets, it was easy access in and out of Venice. General suggestion: You should buy a full day bus pass for €25 or 2 days for €35. These are a GREAT way to get around. The passes can be used to get too and from Venice by bus or tram, and they're also good to get on all the water buses in Venice and surrounding islands, so you can cruise down the Grand Canal, hop on and off as often as you wish, or even take a ride over to Murano (very cool blown glass industry) and Burano. We bought our passes from a tobacco shop down the street on the roundabout (turn right as you exit the villa). Easy!
Have fun in Venice!
