We stayed two nights. One miserably hot. The second very nice. The first night was our fault. We didn't realize there are 4 AC units in the flat. We used only one which was not nearly enough the first hot night so we opened windows which let the mosquitos in to eat us all alive. Night 2 we realized there were additional units. The breakers tripped a couple times so we shut one off and had a nice night.
As for the place, it is large and bright. The kitchen needs cleaning and is missing some basics but it works.
Massimo did not return any communications prior to arrival day which was concerning but he was very communicative and helpful once we arrived. He showed us a great dinner place our first night in.
If it weren't for the first night I would have had a better overall impression. And that's partly my fault. If I return to Venice I'll likely try another option. But we enjoyed our stay.
Thanks Massimo
