The apartment was according to description, perhaps a bit better. It is located near a very good area of pubs and restaurants, we had some wonderful evenings by the canal with the locals and other tourists as well.
You have everything if you want to cook for yourself, there is internet. The bathroom is a bit small but it does the job for a few days. Keep in mind to take some slippers with you as there were none.
The apartment was warm and cozy, that was very nice as the spring nights can get a bit cold outside.
Travel time to San Marco plaza is around 20 minutes but it will take a lot longer because you will stop admiring the city at every step.
Rules of the house are decent and you will feel like home. One tricky thing is how the garbage is collected: basically you need to take it to a special boat in the morning or wait until around 10am for someone to come and knock the door to take it. If you leave on Sunday you will find in the position to be unable to take the garbage out as you don't have where, perhaps a solution on that matter will make this scenario easier to handle.
Overall, it was a nice stay and we liked it, better than expected and most probably we will come again when visiting Venice.
