Paolo's place is very nice and clean. He welcomed us in person and helped us with a few tips as well. The appartment is very close to the train station which, in my case, is very good, so I don't have to be running and worrying to be on time to catch my train. Besides, you can practically walk Venice. You get to the most important sites in 20 - 25 max.
Paolo is always available on the pone and he quickly responded to our messages.
I highly recommend this place.
