We arrived in Venice via a cruise and Gianni provided instructions to apt from the port. However, after arriving at travel counters at the cruise port, they recommended to take a taxi to San Marcos. However, I would strongly advise against that as it took us almost 30 minutes with all of our bags to walk to Gianni's place. If you're arriving at the cruise port, I would just take the 15 walk to the Piazzale Roma and then take the waterbus from there. Since our cruise docked way before check-in, Gianni let us drop off our bags.
Gianni was personally there to greet us at check-in. He showed us all the amenities of the apartment and also showed us how to get to the airport the next morning.
The apartment itself is AMAZING! Maybe a 2 minute walk to Rialto. The apartment is in a big alley around a busy area and we felt very safe. The spacious apt comfortably housed our family of 5 adults, although there is definitely room for at least 8 adults. We were blown away by how nice the apartment is. This is by far the best Airbnb I've stayed at (including places in the US). The apt is clean, modern, sleek, and very spacious. Gianni was extremely kind to provide us with water bottles, juice, toast, and jelly (all of which came in handy for our early morning the next day when no shops were open around us). Each room has an AC unit and the kitchen is fully equipped and spacious. The living room is also spacious and served as a central location for our family to gather in. The 2 full bathrooms were very clean and we were provided with towels and toiletries (shampoo, soap). Check-out process was easy too; all we had to do was turn off the AC and lights and leave the keys on the table. I would definitely recommend this place to anyone looking to accommodate a large family in Venice.
