This is exactly as advertised, a lovely little perch which Laura and Salvatore run obviously "da'l cuore". The charm of the apartment was great, but nothing compared to the gracious hospitality offered by our hosts. Although they respected our privacy at all times, they were right there (they live downstairs) whenever we needed advice or any assistance, and truly went the extra mile for us on several occasions. The place was well stocked with some snacks and juice and various toiletries, and the apartment itself is clean and very comfortable. But it was also extremely charming. The air conditioning worked perfectly and with the windows closed there was little or no noise perceptible. The appliances worked perfectly. It's basically a studio, not very large, but with beam ceilings, a private terrace and a view over a peaceful little campo and one of the side canals, it was a lovely home away from home.
While the neighborhood had its share of tourists (this is Venice after all), the little Campo San Giacomo literally under your window is also a livable place still inhabited by locals, full of children playing and residents enjoying the warm evenings. It includes a terrific bakery and gelato shop and three or four very good restaurants right there, and many more within a few steps. It is a little off the beaten track, which is good, but Venice is not a large place, and nearly everywhere in the City was walkable (and especially accessible via the vaporetti -- water buses -- that run up and down the Grand Canal about five minutes away). With or without the boats, we were able to traverse nearly the entire city from there with no problem.
If stairs are an issue, note that it is described as an "attic" and so there are about 50 steps up, and no elevator, of course. We did not find it to be a problem at all (and Laura offered to help with the bags, although we didn't need it). But nevertheless, you should be aware.
In any case, all in all, a great place, a great value and a great experience if you are looking for a place where you can feel like a local in the midst of a very touristy town.
