This attic apartment was perfect! My wife and I stayed for 3 nights. It is within a 15 minute walk to everything we wanted to see, and most importantly just a 10 minute walk to the train station where we had to carry bags. We had some trouble reaching the apartment for check-in since our phones were not yet activated and we could not reach the hosts, but a nearby shopkeeper helped us connect with Ketty who was very gracious about our oversight and got us back on track shortly.
There are good places for breakfast right down the street and at check-in Ketty gave us suggestions for several other great restaurants within 10 minutes.
The apartment has a beautiful view over the city in three directions. I'll repeat that the location is perfect: it's close enough to easily walk to the major attractions like the Doges Palace, but just far enough to escape the crowds. Our visit to Venice would not have been the same had we stayed anywhere else!
