The location is perfect as a base to explore all of Venice.
If you are a light sleeper bring earplugs because streets in Venice are loud until around 4am. Also, the beds are NOT comfortable, to the point it may be an issue.
The apartment is nice, clean and definitely taken care of, but stocked with pretty much the bare minimum (i.e. hand soap only; no shampoo or body soap, minimally stocked kitchen). I would not consider this place an AirBnb Plus.
The host was very responsive and provided a nice check in experience.
