This is a gorgeous apartment- large, light filled, tastefully furnished, with a state of the art kitchen looking out through double glass doors onto a balcony over a small canal!! Most rooms also have air conditioning, which we really appreciated.
Our contact Maria was responsive when needed. The master bedroom was huge, with a very large wardrobe- so luxurious! We were fine, but it should be mentioned that the really large and comfortable bed is very low, should that be a problem for someone. There are stairs to the first floor (ie. second for North Americans), but that makes the air less humid.
Finally, location also is great- very close to a large square with restaurants, and a church that had a lovely concert we attended one night- Vivaldi's Four Seasons and more. Really excellent! The apartment is walking distance to most places, including San Marco (St. Mark's) etc that one would wish to go.
Highly recommended.
