Francesco and Nina were very helpful and responsive before our stay, providing very detailed instructions on navigating the city, finding restaurants and where to go, what to watch out for, etc. When we arrived, we were informed upfront that the toilet flush wasn't working. While it posed some inconvenience, it did not affect our stay much. We were also reminded by Francesco that they were only a phone call away, which was assuring. Overall, we enjoyed our trip to Venice.
