This is a great location only a 5 minute walk from Rialto bridge and 10 minutes from St Mark's. Two small grocery stores are real close. The two bedrooms are HUGE and the place is very clean.
The only downside for a place between Rialto & S. Marco is the street is always busy with people and you need to close the windows at night to keep the noise down.
We would definitely recommend this for two couples or a family.
