I stayed 4 nights with Anna and her son Samuele and had the most wonderful time. The were super friendly and made me feel right at home. The room is nice and quiet, with a great view out to a small canal. It has an ensuit bathroom with shower and the bed is very comfortable. The location of the flat in Dorsoduro is perfect - you walk to vaporetto Linea 1 on the Grand Canale about 2 minutes in one direction, the other direction brings you to Linea 2, 5 and 6 after about 7 minutes of walk. Everything is easy to reach, even just on foot. The area around Campo San Barnaba is also very nice, lots of great restaurants, bars, bakeries etc right at your doorstep. I do hope I can stay with Anna and Samuele again some time!
