Staying at Lucia’s place was an experience. Lucia is very passionate about Venice and is happy to share that with her guests.
As other folks have said, there is no kitchen. Breakfast is provided sort of - there’s a variety of snacks and packaged foods which wasn’t totally our cup of tea (there is a lot of tea!!!). There is a kitchen in the unit but she keeps it locked. We weren’t in Venice for too long and wanted to maximize our time there - quick note that our check in process took about 1.5 hours. Lucia showed us every single thing in her apartment, gave us tiramisu and then walked us throughout the city for about 45 minutes. In theory and definitely for many people, her insight and suggestions are great but just know it is pretty lengthy.
Her apartment is very close to the train station - St Lucia and Piazzale Roma. Just about as close as you can get which is great. Lucia is very kind, she is particular about her space and her things (just like many have noted, you can’t bring any luggage into her apartment. With or without wheels. Including your personal backpack...).
