We chose to stay at Donata's home while visiting Venice because it was less expensive than staying in Venice itself. We were worried about the commute at first, but the water transit system is nearby and very easy to use. There are boats going to and from Murano island 24/7, including direct boats from the airport, train station and Venice. The closest stop to Venice takes only 15 minutes.
The house itself was older than we expected, but homey. At times, the front door was difficult to lock and you had to play with it for a few minutes. Don't expect to get too much laundry done here either, there is only a small washing machine and an equally small clothesline out back.
Donata gave us a portable WiFi modem that came in handy because you could take it anywhere with you. Overall a clean, cosy place I would recommend for couples. Donata was helpful and responded quickly to anything we needed!
