Hello. The best island for me is Curacao. I think the balance between price and quality is very good. The island has many historical monuments, many beautiful beaches and many features that can make your experience a great one. As far as renting a home, you have many options. I rented a house from the company
CuracaoRentalHomes. Personally I stayed in the villa Kas Kinikini. They have decent prices and are very professional. I had a great time! Hope this helps you!
