Paolo's place is conveniently located near the Vaporetto Ospedale stop, which is 30 minutes each way from the Venice train station. Though the place is not located inside of the location circle shown in the initial booking, it is still within walking distance to all the touristy places (20 minutes to Doge Palace). An added bonus of being a little further away is that it was a very quiet stay for us, and the bedding was very comfortable.
In case you need additional supplies, they are tucked underneath the bed. To open it, lift up from the foot end of the bed, and it will stay open at a 45 degree angle.
