The listing is very accurate and the location perfect. The place is quite small (as expected), and everything worked nicely. Just what we needed, and we were very happy with our choice of place to stay. We had amazing 5 days in this place . The location couldn't be better, steps from St Marco but still in a preserved spot. The entrance of the building is surprisingly ugly, it is a small side street and many of the nearby buildings hang clothes on top of it.
Do not get (badly) impressed by it. Once you enter the building everything is nice.
Unfortunately I have not met Gabriele to comment, but he was quite helpful by email.
