Stay at Rosanna's place was nice! It was beautifully decorated, very spacious (perfect for a group of 4) and well comunicated.
Fontamenta nova station is just 2 minutes and Rialto Bridge about 10.
We missed some amenities very helpful for a short stay as dish machine pods, kitchen cleanning stuff or shower gel. Besides she just left the leftovers of basic food (sugar, salt, oil...). We had to call her the day before to claim for check in details.
A good place to stay in Venice but some details to improve for a perfect stay.
