If this apartment is available, you should rent it. Now. It's beautiful (decorated with very tasteful local art), centrally located, and the hosts were the best.
Our family of 4 was very comfortable. In fact, when my cousin surprised us with a trip down from Munich, they were very gracious and had no trouble with her spending the night. The 5 of us were comfortable.
But most important to us was that when disaster struck after we had checked out (we missed our ferry--moral of the story: ferries in Italy sometimes leave early from different docks than are printed on your voucher), and we were trapped in Venice on a very busy August night with no place to stay, they happily took us back to the apartment. They even made arrangements for our travel the next day and volunteered to print our tickets. It was so comforting and helpful after what had been a stressful afternoon. We will always look for Lotus first when we come through Venice.
