We thoroughly enjoyed our stay at Luisa's apartment for 3 nights. The apartment was not only within a few minutes walking distance from the Piazzale Roma (easy to arrive and leave Venice), but it was also within a few minutes walking distance to the main vaporetto lines (easy to travel within Venice).
The apartment was beautiful and well-equipped. The heating system was well-maintained, and kept us warm through the chilly nights. The wifi was stable and reliable. And there was an unending supply of coffee powder and tea bags!
The icing on the cake had to be our wonderful hosts Luisa and her daughter Nicoletta. They actually came to the station to pick us (something we have not experienced with other AirBnb hosts), and they gave us a gigantic panettone (Italian Christmas bread) and a bottle of sparkling wine as a welcome gift. Throughout our stay, Luisa was extremely responsive to our queries on WhatsApp.
We would highly recommend Luisa's place, and we would choose it again if we returned to Venice!
