Great stay! Sofia is a wonderful, thoughtful host. Apartment is clean, well-maintained with the typical uneven floors (so you know you're in an authentic Venetian home), and everything you could need (even AC in the bedroom, which was very necessary when we were there). I would recommend a sleep mask as the room is quite bright in the morning.
Excellent location, about equi-distance to Ponte Rialto and the train station. Loved the local life of waterfront bars for happy hour just outside the apartment building--we felt immersed in Venetian culture immediately.
