Aaaahhh, found a great looking villa that met all the parameters; size, price, location, only to find it is not available the week we are travelling! Someone on the forum recommended it - Island Time. Back to the search!
NancyB - Cliffside looks nice but I have an issue with stairs and I also have a toddler in tow. I'd like to keep kids bedroom in the main part of the house. I like Miles Away for these reasons but the price is a little higher than we are shooting for...
Sea Dream, Seabiscuit, and Amorita are lower priced options that appear to have interior access bedrooms. I haven't stayed in either but they were some I considered in my search for a 2-3 bedroom with interior access for little kids.
