My girlfriend and I had a lovely time in Mara's flat. The flat itself is very pleasant and has everything you would need for a week's stay: comfortable bedroom, open living space/kitchen and a nice clean toilet. It was also very easy to get into Venice every day, and we enjoyed being outside of the islands. There's also plenty of shops etc very close by, meaning you can stock up as you go.
Mara and her sister were very kind in picking us up from the train station and showing us the area a little bit. Overall it was a great experience, I very much recommend it!!
