The apartment was beautiful - light airy and very comfortable! The location was a very easy 15 minute walk from the Water Bus Station and there are lovely wee restaurants and markets near by. It's a really easy hop over to Venice on the water bus and the 72hr travel pass is an easy way to get around. We also found that if you're under 29 you can get a cheaper ticket with the Venezia Unica City Pass - the woman at the ticket office sorted it automatically for us but might be worth asking if it isn't offered.
Sylvia was an amazing host, she came to pick us up from the boat, took us to the apartment and then gave us a wee tour around Lido before taking us back to the boat to go over to Venice. When we left she also picked us up and took us to our boat early in the morning which was extremely kind of her. She also recommended some great restaurants and things to do around Lido.
