Anna is a very friendly and helpful host. I would say that the best advantage of this appartment is its location. You can practically walk to most points of interest in Venice, as it is situated near the Accademia bridge.
We really enjoyed staying there. Many trattorias around for an affordable dinner.
If I may mention two minor details: it is a narrow street and you do hear what people are talking about when they walk by (but this is probably similar everywhere in Venice - this didn't bother us, as it was wintertime)...
...and it is a small adventure to get to the balcony :)
