This location is amazing and the room is perfect for one person. It is very basic, as others have said, but you aren’t in Venice to stay in your room. Stefano is incredibly helpful. From clear directions to help with finding a phone charger, he was fantastic and responsive. An ideal host.
The down sides, the walls are very thin so if you are a light sleeper this might not be the place for you as the room is next to the bathroom for another room and your will here them. I also made the mistake of leaving the window open one night for air flow and got eaten alive by mosquitoes. (No one’s fault but my own) The shower is also small as others have mentioned. But like picture it even smaller than you are currently thinking. Like tiny tiny tiny small.
Even with those downsides (mostly beyond their control), I would stay here again if traveling alone. I cannot stress enough how amazing the location is and how great the host is.
