All the first floor condos at Belmar are two bedrooms. But they're priced the same as the one bedroooms. The master bedrooms are on the street side so no view, but they're spacious, even the master bath is large.
The only one bedrooms are upstairs. And the stairs are circular. Not too easy on crutches.
They have a nice pool though a little small - all tile bottom. It's about 20-30 ft. from the middle first floor condo patios. The ocean is 20-30 ft. past that, down about 7 or 8 stairs to the dive dock, then down 4-5 wide stairs into the water. It's pretty shallow there but there's some coral rubble mixed in the sand just off the dock so with something to protect his feet he could wade in the area. There's no beach there, BelMar sits on a low ironshore cliff. The nearest beach is Bachelors, about a block north. And not much of a beach, it's a named dive site also.
There's no restaurant or bar at BelMar if that's something he might want while you're gone. Their inhouse diveop is Buddy's so if you don't find someone to dive with at BelMar drive over to Buddy's where you'd be hard pressed not to find someone. I think they send the boat down from Buddy's to pick up also now for boat dives - It's not docked there, contrary to the picture on their website.
The good thing for you about BelMar is that the entire property is very compressed, it's only about 40' from the parking lot to your door. The diveshop/office is on one end of the property and the tank pickup is right off the street.
The first floor condos have their own dive lockers outside the back doors and they stock tanks on the dock so the gear hauling is kept to a minimum. There's a rinse tank and shower right on the dock. About the only time you have to go to the diveshop is to use the O2 analyzer for Nitrox.
The BelMar house reef has a gradual drop, it's one I'd do solo. Not the best dive on the island but better than what's at some of the other dive resorts. If you wanted to do it at night, they have lights in the water also.
It's a nice place and very quiet at night. I think it's one of the newest places on Bonaire, Den Laman being the other.
