Thanks to all. The place that is no longer available, Sucrier, was in Residence Les Lataniers. It was a ground floor unit - no stairs. I checked out Studio Costa Caraibes on Air B&B, but it only has a Queen Bed. I will wait until airfare for a March 15, 2025 is posted at the end of the month, or around the beginning of May; before booking the rental. I also checked VRBO, but their prices seem much higher than those posted on AirB&B.

If we were younger, we would not mind stairs so much, and would probably not mind walking down from the Mt. Vernon every day.
