This is a place that I'd totally recommend. It's really cheap (consider that Venice is REALLY expensive), the location is just perfect, close to Rialto and close to San Marco, still is a pretty silent appartment without the noise from those loud tourists (so you can sleep well!). Maybe the internet might work bad from time to time but take in consideration that you're in Venice and it seems to be kinda usual. For a single traveler who's more eager to visit and walk thru Venice, it's the place you're looking for.
