Serna's house is an old fashioned Venetian house that has been renovated. It is perfectly located on Guidecca island just across a narrow stretch of water from San Marco, the main island which is serviced by a couple of ferries that leave every 10 minutes. It is a quiet and perfect location from which to visit all the sites. The house has some windows overlooking the water and is air conditioned, which is high recommended in summer. Serena is a lovely host and very responsive. Recommended.
