Nicola was very friendly and helpful. The place is great. Good location, 2 minute walk from the boat stop and 15 minutes walk to San Marco Square.
I would recommend a bit better cleaning, because not all the sheets and towels were clean. I found some clean ones in the wardrobe and changed myself.
Tap water smelled a little weird, it was impossible to make tea with it. I don't know if it is normal in Venice?
Nicola please, you should pre-heat the place during winter time, because it was really cold on the first night. We were with children and it was terribly cold.
Besides these smaller problems we really enjoyed our stay.
