We spent 3 nights at Susanna'a apartment. We had an excellent stay.
The apartment is located about 5 minutes away from the ACTV vaporetto stops coming from / to the Ferrovia (30 minutes away with line 5.1) and the Aliguna line from / to the airport (60 minutes away, via the Lido and Murano). The apartment is very well located to visit Venezia or the Biennale (5 minutes by foot away fail Giardini Biennale). It is located in an area where local people live. It is much better then to stay in the touristic area (hotels or apartments) because you see local people and no thousands of tourists queuing in the street.
Susanna's apartment is very quiet. It has everything you need to cook and have meals, which we did twice; there is a COOP store a few minutes away on Garibaldi street that provide all the food you need. There is also a fruit and vegetable street shop opposite to the COOP where products are really good and surprisingly very cheap. And there is a restaurant called Nevodi next to these 2 shops that serves excellent local food.
The apartment is made of 2 rooms (one of them is an open kitchen) + a bathroom with a shower and a washing machine for clothes. Maybe 50 m2 in total.
It was very easy to communicate with Susanna (and her husband David). There were very accommodating for the arrival and departure dates.
