Our experience at Elenas place was decent. Quick snapshot.
While the host had some one to greet us at the boat bus station ( and that person had to wait for some time as we missed our train ), may be she was in too much of a hurry. We didnt get the feeling that she wanted to give us some tips / suggestions at all.
The place per se is located nicely but the house is really really cramped. I wont say its very different from the pictures but it is quite stuffy. There is no real ventilation. There are two coolers which are super duper dirty. ( Have pictures ). The bathroom is ok but the kichen again is super duper small. May be its a Venice Problem. I dont know.
Elena however was super sweet. She gave us suggestions when we were not getting a bus. She was approachable on the phone. But since we were there for just a day, we didnt want to make a big fuss about it.
