Gianni is very responsive in communication. I didn't get to meet him, but his friend Reta checked us in and gave us a ton of helpful information like how to get to where we want to go and tricks to avoid tourist trap. Being a first timer in Italy, the information helps us a lot.
The place is a big house divided into multiple guest rooms. The room we got was different from what is shown in the listing. Though the room seems to be newly renovated, clean, and brand new, it was unexpected.
The location of the place is in a residential neighborhood. We get to see the life of locals - sport bar, local convenient store, grocery shops...all the non-touristy stuff, yet we can get to Venice island easily. People in that neighborhood speaks little English, but we had no problem getting around. It is fantastic if you are into seeing life style of Venice locals.
Overall it was a smooth experience.
