This place is in fact incredible for it's location. Best way to get there is on the ferry from the Airport, which Francesca did a great job getting us instructions on. The price is roughly 15 Euros per person. Expect to be on the Ferry for 45 mins to an hour, but hey, you're in Venice so enjoy the view and ride! Once you get to your stop, San Marco, the apartment was a 2 min walk! The stairs are a bit steep and your going up 3 flights, so pack light!
The place was clean and the bed was comfortable. Only drawback was that shower was hard to use. The water pressure is not that great and we couldn't get it to stay warm. It would run cold then hot. This wasn't enough to ruin our stay because our hostess was very informative and kind. The location is amazing, because you are feet away from restaurants, gelato and San Marcos square. Nights weren't that noisy for us, just make sure to close the window covers. Overall, a great place to stay!
