If you're looking for a quiet place to relax in after at busy day in Venice, book now.
Our family stayed both in #3 and #4 during one week June and all I can say is: awesome! The communication before the trip was very effective. Fabio's wife Andrea was at the Vaporetto-stop to meet us as we arrived and made us feel very welcome. I highly recommend this place: the views from especially #4 are such that you can just sit and watch the sea and the traffic for hours (OK could have, if it wasn't for the kids).
And a special thanks to Fabio and especially Andrea for helping us with everything! The only problem was that our kids didn't wan to leave at all :)
