Marco's assistant let us in to the apartment after we got off the vaporetto. If you're traveling light, it's only about a 15 minute walk from the train station. The apartment is large, bright, and has a comfortable bed (plus space for more to sleep in the living room).
What makes this place great is the location- behind a gate, in a nicely landscaped yard you'll find the apartment tucked in with a few others. It's only a few minutes off the main tourist route but it is very quiet, private, and secluded, just a few steps from one of the many minor canals running through the area. You'll have countless options for less touristy dining nearby, as well as unique photo ops in the windy alleys.
One thing to note is that this was more of a
"Here's the key, call us if you have any problems" kind of setup. If you're expecting a super engaged host with a ton of personal recommendations, you might want to look elsewhere. If you're happy to be left alone to your own devices in a wonderful part of Venice, then Marco's place should be perfect for you.
