The place is comfortable and clean, with enough space to accommodate at least 3 people (1 double bedroom and the sofa bed in the living room)
Communication with the host was easy and they were responsive, they even gave us a bus ticket when we arrived to easily go and reach the station where we could buy our passes for the next days
The place is not close to the island of Venice, but there are many easy ways to get you there (2 buses less than 5 minutes away, and the tramway to get you to the central train/bus station right in front of the building)
The buses are the most convenient to get to the island, there are no changes on the way, and you will be dropped on the island where the boats to visit Venice will be waiting for you. The journey will take around 30 minutes total.
It is also easy to spend the evening in Venice and have dinner there. The last bus to go back to the apartment will be at around 00:00 (I recommend downloading the CityMapper app to easily get the timetables of all the transports in Venice and The surrounding places)
Overall this is a nice place to visit Venice without paying for a more expensive place directly on the island
