It's a great location, right next to Piazza San Marco and very easy to get to from the airport by Alilaguna to S. Zaccaria. Checking in was very easy - we were in touch with the host over WhatsApp, let her know when we were leaving the airport and when we had arrived nearby, and within minutes were met and taken to the apartment. The place was clean and as expected, and all the essentials were there. Check out was incredibly simple too. You could probably pay more for another place and get a slightly bigger kitchen or a water view, buy why? Get out and use that money for another dinner and bottle of wine at one of the countless restaurants instead. If you're spending your time in an apartment rather than getting out around the city then you may as well have just stayed home rather than coming to Venice to begin with.
