The apartment is very centrally located, a couple of minutes walk away from Pza S Marco, in a very quiet cul-de-sac that is not that easy to find the first time round, but then is relatively easy to remember since it is in an alley right next to a very good ice-cream shop.
The apartment itself is very spacious, and provides very well for hanging around in the relatively large living room that is perfectly located overlooking a corner of a canal which provides a very pretty view.
The host was fine overall, and very accommodating with the early check-in, however did make some rather strange requests, like not to use the dining chairs as they are fragile, or not to use the single air conditioning unit at length because electricity is expensive! Oh yes, there is only one proper A/C unit, as one of the other rooms has a portable unit that is not very effective and the other room has a small portable fan, which had to be used in the living room to keep us from melting away when we stayed there in the evenings. The place could do with some additional fans to make up for the lack of A/Cs throughout. The only other point worth mentioning is that the electricity is a tad sketchy but overall works ok.
Other than the above, the place was lovely, had everything else you would need for a 5 day stay in Venice, including an on site storage area for luggages, and was very centrally located to everywhere we wanted to visit.
Will definitely recommend to others, but please do add some more fans for their sanity! :)
