This was in Cannaregio and we loved this area. We are from the midwest so the September, October kind of weather is what we like the best. We are looking forward to a visit back to Venice soon.
This from someone who is spending two weeks in Venice in November, the month of most precipitation; I couldn't bear to put my (10th or 11th or 12th) visit off until January.
