First of all she gave us improper directions for her house, she didn't even know the trams coming to her home. When she gave us the directions for her place, she only gave one option of transport which was not available. Therefore, we had so much trouble to find her place.
Also, the location of the house is not very convenient to reach Venice. There are far better places available in Venice island as well mainland. And you may have a hard time to reach there at night.
The room was spacious as described, however there were large glass windows and large glass doors with transparent curtains. Now, this kind of room might be sunny and airy for some guests. However, there is no view to look at, only buildings nearby, hence not providing any sort of privacy. Again, there is no bathroom in the room so you have to go out of room for change of clothes etc. Also, being summer, with those big windows and west facing, the room got very hot in the evening.
The AC of the room was not working, so we had to sleep dripping with sweat in the summer of Venice.
All in all, not all worth the money and traveling effort.
