We've stayed at many condos and vacation rentals throughout the Caribbean, Florida and Central America. We opted to go back to St Maarten because of the people, ease of getting around, the food, culture, beaches and snorkeling. What makes it particularly unique is the French side and the Dutch side. Rainbow Beach Club is on the west side of the island (Cupecoy) located about a quarter of a mile from the French side. It's an older property, but not outdated. This is the "gold coast" side of the island. Both pools (one salt water, one freshwater) were very nice. This unit overlooks the salt water pool, the sunsets, the ocean and part of Simpson Bay shopping/beach/casino area. There are many options for food whether pizza, BBQ, Italian and French, including more upscale within 2 min walking distance. Cupecoy Port, is also a safe short walk or 2 minute car drive with restaurants, shops, and even a casino along with Cupecoy beach across the road. Eating alongside some pretty nice yachts on the port was a nice experience. We had a car so visited Grandcase, but liked Marigot much better given it's stores and the Market. Phillipsburg is a 25 minute drive for the boardwalk and Front street shops. Divi Bay near Philipsburg has the best snorkeling from the beach. The beach located in front of the unit is small and situated below a cliff. It has a lot of wave action, but is THE most picturesque. You'll take amazing sunset photos from here. Hands down our daughter's favorite (19 year olds). They took so many amazing photos, people were in awe.
As for the unit, I'm going to say if you are looking for all new and top of the line fixtures and appliances (the Ritz), this is not for you. However there is nothing "bad" it's just aging and has been maintained very well. When we walked in we could tell and smell it was freshly cleaned. Beds are medium, more on the firmer side. No complaints. Susan periodically checked in on us which I truly appreciated.
The value for location and all the above cannot be beat. If you want to tour the island, suggest renting a car across the road and also getting supplies from the market across the road. They have everything, not joking and super nice.
