We had a pleasant stay at Paolo's place.
The communications with Paolo were great. He provided clear check in information and was straightforward about what he needed from guests (passport photos and extra charges in cash.)
This is a good place if you absolutely have to stay in a local apartment and not in a hotel. It was interesting to see how locals live. The place has tons of character.
The place is located in a safe neighbourhood three minute walk away from the closest vaparetto stop. If you don't have luggage you can even walk there from the train station. The place is on the third floor so be prepared to drag you stuff upstairs.
The bedroom was good with a comfortable bed. The living room was nice and like on pictures but we ended up not using it. The kitchen was quite seedy but equipped with everything necessary for a short stay. The washing machine was a great addition (and we got to dry our clothes on ropes below the windows like locals!) The was no coffee machine though.
The bathroom had some mold and the wall area around the tub could be cleaner. There was no curtain on the window, so we had to hang a plastic bag for privacy. The shower hose was short and not comfortable to use, but it was ok for a couple of days.
Overall it felt like the apartment could benefit from some investments but it was good for a 2-night stay.
