Overall this is a great place to stay. It is under a 10 minute walk to piazza del san marco/the basilica and about 15 minutes to the rialto & other sights to see that direction. Lots of nice little shops & restaurants on the side streets right outside the place and on the way to the main attractions. The description of the lodging is a little unclear whether the sofa bed is a pull out sofa that would sleep more than one - it says sleeps 6 with a king bed, king bed, and a sofa bed. It actually is a king bed, king bed, and two sofas that each sleep 1 person. Each room had a wall A/C unit to keep it cool in the June heat. The shower was very small, but manageable. Just be careful as the pipe/faucet in the shower get VERY hot and will burn you.
The host met us at the water taxi drop spot but we felt rushed as he was walking us to the apartment. He literally said "we need to hurry because I have other guests to check in". We later messaged the host for recommendations for local restaurants etc, but he did not respond. We had great luck with recommendations from locals at our other stays so we try to do that everywhere we go, but we did not get a response from this host. Overall though it was a solid place to stay for the location, cleanliness, quality/size for 6 people!
