The apartment is really nice and big. We were 4 and felt very comfortable. Instead of Silvia Cristian welcomed us directly at the Vaporetto stop Giardini.
The location is great; hardly any tourists and all shopping facilities (bakery, supermarket etc) as well as nice restaurants are around the corner.
If you are interested in art (Biennale) then this apartment is superb. Giardini is less than 5 min away and going to the Arsenale might take less than 10 minutes.
We can highly recommend this place!
