Lasenza,
I'm not sure all your needs will be met at any one location. There's a new resort south of town that looks pretty nice. Beautiful pool. I imagine they're pricey but I don't know for sure. Luxury defined by nature - Delfins Beach Resort Bonaire
There was some discussion about car rentals. I'm a fan of AB (and full insurance). Very well run and good vehicles. And if you do have a problem with a truck they'll take care of it quickly. They've always had someone right there to pick us up at the airport.
I have some experience with Delfin's. It is one of the nicest resorts on the island and Dive Friends has a dive shop and fill station there also- which is a plus! Pool is amazing. Nice, but expensive restaurants as well.
It is quite pricey, unless you can get some sort of a special deal or if money is a non-issue. Another thing to consider is the house reef. If the plan is to do lots of dives on the house reef, it is worth considering that it is on Punt Vierkant. Conditions there can be variable due its location on the point (wind and current sensitive) - I have experienced 5 foot waves crashing the shore there and then traveled a kilometer north to Bachelor Beach to find conditions calm and glassy, the reef is a pretty decent kick from shore too.
