Those two are both at the Villas at Great Bay, which is in P'burg. I personally would not care to stay in Philipsburg. There's lots going on during the day, but not much at all at night, so you'd mostly have to drive to somewhere else, like Oyster Pond or Simpson Bay, for dinner. If you like to see cruise ships close up and LOTS of cruise ship pax walking by your beach, the units themselves look nice.

Regarding La Siesta, I have heard some concerns regarding security there in the past, because it's in a residential area. I have never been inside the units though. Disappointing if the beach isn't the greatest there. If it were ME, I'd book at Beachside Villas! Cheaper than any of those choices, and on the very best part of Simpson Bay Beach!
