We had a great stay at Massimo's place.
He was very good at communication with us from the beginning.
Pros:
Very spacious! The apartment has tons of room and the bathroom is very spacious as well!
Good location: Venice is very walkable and the apartment is just 15 minutes from the central train station.
Great communication: it was easy to reach Massimo through whatsapp whenever we needed something or had a question
I would highly recommend taking a boat tour with Massimo too. The Gondolas are more expensive and don't see as much of the city.
Would definitely stay again!
