I can totally recommend this apartment.
The location is a 5 minute walk away from the rialto bridge and about 15 minutes away from St. Mark's Square.
In my opinion the location is really good.
The view from thw window was also just beautiful.
Very important: It was very quiet. I didn't hear anything during the night, and therefore we could sleep very well.
The flat is also big enough for four persons (it has two beds, so you have to share a bed).
The kitchen is also big enough.
And the bathroom is great. It has a wonderful shower.
We enjoyed our holiday in venice!
