Guigi is a great host and we enjoyed our stay very much. She welcomed us in the late evening hours and offered nice chat and some local advice.
The apartment is huge for venetian standards and there are only 2 rooms rented out so it feels very spacious. Bathroom is big and comfortable, you get to use the kitchen and fridge. Location couldn't be more perfect, it is literally 3mins from Rialto and there are tons of bars and restaurants nearby.
The only drawback is that it is the last floor of a tenement. It was not a problem for us since we are rather fit but just be mindful of that.
