We were 6, and spent 2 great night at Ca' Donzela, during Carnevale. 3 nice bedrooms (one big, like a very nice hotel rooms, the other two smaller, but ideal for staying in Venice and come home only to sleep). The kitchen is very well equipped, so you can also cook, we only had breakfast there because we ate out, but can work well if you want to cook at home. The market just around the corner has wonderful fruit and vegetables, and you can find bread, pasta and cakes in the many shops nearby. Perfect location, one minute from Vaporetto to anywhere, and nice 15 minute walking distance to San Marco (even less with less crowd). Only defect , if you have a light sleep, is that in the morning you can hear very well the noise of people setting up the market, but I was the only one, among 6, to be waken up by that. Arielis is very nice, and even if check out is at 11 she let us stay all day, so we could leave the suitcase there until the time to go to the station. Highly recommended.
