My parents stayed 3 nights in Leonardo's place. He was not in the city and didn't answer his phone, so the communication was not the best. The place is very old, which is not surprising in Venice. The toilet paper had finished and there were no more available in the house! the weather was also very hot. It took me about 14 hours to reach leonardo and ask for a fan, which he provided after the first night.
General experience was not pleasant and I won't recommend the place.
