This is an A, 90+, but just missing a few items to be truly A+, 100. To start, the location is great, right off the Accademia and Zattere vaporetto lines, and most sights/restaurants are within 15 minutes walk. the unit is large with an oversized living room and the unit design and furniture has a very refined, old fashioned feel. The windows and the views are fantastic for those who want to capture a pic/memories of a canal and bridges from the comfort of a vacation home.
The unit is quite clean for the most part but here are some of the improvements. Not sure if it's us, but seeing hosts go into units/check in with shoes on is a pet peeve, makes me wonder how clean the floor is to begin with. The shower is quite modern with 3 different head/spray settings, water pressure great, but there's some black/looks like mold in the corner of the shower door. the toilet paper holder needs some tlc to keep it from falling apart.
Lastly, and really not something the host can do much about but worth noting for other travelers - there's facade restoration work across the canal so the view wasn't perfect when we were there and it gets quite loud in the morning. And it's direct view into the unit if you don't close the shutters (optional, but then there's no morning light). Since the unit is in the middle of a lot, noises can go on till pretty late with people downstairs - nothing that kept us awake. And when we visited, the elevator didn't work, something the host told us about at arrival - again nothing that we were upset about, but worth noting for other travelers.
