We just returned from our stay in the 1bd/1bath unit at Villa Eau Claire. Location is great; away from the hustle and bustle of town, but close enough that you can get just about anywhere on the island in 20 minutes. The small beach below the villa is perfect for swimming in the bay without the crowds at Magens Beach. The view from the balcony is great as you can watch the larger sea life swim by; tarpon, rays, turtles, and a barracuda or two, while the birds dive in the water after the small fish. The water is calm enough for small children (our 5 year-old loved it), with enough sea life to keep older kids interested (green moray, urchins, thousands of tiny fish, a handful of different reef fish hanging out in the rocks on the shore and sea grass just off shore).
The 1 bd/ 1 bath apartment is well appointed. Good for two adults in the full-size bed and a smaller child on the pull-out couch. The pull-out doesn't have enough support to comfortably hold an adult. There was a nice breeze most of the time and we didn't use the A/C. Highs in the mid-80's and lows in the low-70's. Kitchen had everything we needed, and if it's not there, just ask Julia, as there's a good chance that she can provide it very quickly.
