ICI casa Murano has everything that you need and I can recommend it. We have been there with 7 people. Everybody slept comfortable and there are two bathrooms, so no worries.
The kitchen is super equipped and the wlan is working great.
The rooms are outfitted differently and you have to take a close look to see all the details.
When you are there in summer the best part is the garden, it has a big table, comfortable chairs and enough space. Also you have sunny and shadow places because of the tower in the back.
I loved it to live in Murano, you are close to Venice, Lido and Burano. But its not that crowded like Venice.
There is a shop and a good Pizzaria near the house.
