Luca goes well above and beyond what you would expect from any host. He is available 24/7, and offers great services in addition to accommodations (luggage storage & transportation to/from cruise port, train station, and airport). While the apartment is not on the main island in Venice, it is a very easy bus ride there. The location is not as central, but this is arguably a nicer way to experience Venice (and much cheaper!). 100% stay with Luca if his place is not already booked!
