are you specifically looking for a "villa". If not, we stayed 6 nights at Da Reef Apts in a two bdrm/2bath. Even though it was just my husband and me there was plenty of room if sharing with another couple or single. Grounds are gorgeous (no pool though). Has full kitchen balcony dining and living area. They have smaller units also.

It is literally a minute's walk to Lower Bay Beach where there are lounge rentals, two restaurants, snorkeling from beach etc. We loved it.

here is a good website with various accommodations, unfortunately Da Reef's ad is horrendous and does not do the place justice.
