It's a wonderful flat with a lot of space and a wonderful view: the balcony is just above a canal and we can see the gondolas from the flat and hear the gondoliers singing.
It is perfectly located between San Marco and Rialto bridge (10' each side ... except if you get lost which occurs frequently in Venice but this has nothing to do with the flat).
The air conditioning was very appreciable since Venice can be wet. The flat was really clean and was cleaned again during the week.
So we really had a wonderful week in Omar's flat.
Bref, un magnifique appartement!
