I am very confused on the transportation options and costs to go from the airport to our apartment. Keeping in mind that we will have luggage and 2 of the 3 of us are in our 70's, does anyone have any recommendations with ways to go and costs? TIA
Which airport?
You can take a taxi
If Rome-fixed rate 50 euros
Go to the official taxi rank in front of terminal
ETA
Oh is this Venice?
Take a water taxi -about 130 euros
You can book in advance or book at the airport
Official water taxi

Water taxi will get you as close to your apt as possible
You might want to ask the landlord for more specific directions
When I search " Corte del Santissimo" I get a result in Venice.
Ask your landlord. Unlikely you are the 1st customer needing to get there from the airport.
The easiest, most convenient method is likely to be the most expensive. ( i.e., water taxi)
