It was a decent place to sleep for a single night. Nicola is was very friendly and helpful. Good location.
I would recommend cleaning a bit deeper. E.g. dead mosquitos on the walls/ceilings.
I would recommend to add a repellent or spray for the guests as there were a lot of mosquitoes flying around.
The apartment is on the other end of Venice and well located, a 2 minute walk from the boat stop (it take about 35 min from the train station to the stop by boat).
