We had a great time in Venice, and Alessandro is a great host, responsive and helpful. He met us to take us to the apt, he's full of information about the area, and charming. There were good and bad sides to the apartment, but most of all, it didn't stop us from having a good time.
You couldnt ask for a better location, you have so much on the doorstep and it's located in a much less touristy area than other places. It's cheap compared to lots of other apartments. It's large. We were a party of five and it accommodated us very well (the kitchen is on the small side, but totally fine and you'll be eating out all the time).
Tonolo, directly below, is a fantastic patisserie, where you can stand and have coffee and a breakfast pastry with venetians before they start their day- was so buzzy at 9am.
The downsides - be warned showers were a dribble (although Alessandro did say that Venice has a problem with water pressure - so this could be a problem all over). This means that only one shower should be operational at one time - which Alessandro advised. One other thing to be aware of, although the apartment is in a great location and it's also opposite a very lively bar. Which was only a minor problem on Friday night and it died down around 1am - all the other evenings the windows kept out the noise.
I'm pretty certain that the apartment is run professionally as a let, which is fine, but it isn't someones day-to-day home, if you're looking for that experience. The main issue was that it wasn't as clean as it should be and needs a real deep clean, there were dead wood lice, a very sticky patch on the floor, dust in all the corners and bath mats weren't fully cleaned.
If you want somewhere cheap, in a great location, and don't mind too much about a really clean place then this apt is fine. And if you do go for it, you'll have lots on your doorstep:
Tonolo for breakfast (even though you can't sit), La Bitta definitely the best choice of restaurant close by, red caffe on Santa Margarita for cheap spritz and fine gelato at Grom on San Barnaba.
