We stayed at Terry & Bob's place for about a week. It was a great place to live like a local. There is a supermarket about a half mile away, and a well equipped kitchen.
We rented snorkels for a week and went to the nearby snorkeling spots. One thing to be aware of... there aren't many real sidewalks on the island. So while there is a good spot for snorkeling about a half mile up the road, you have to walk on the side of the road or drive to get there. The closest sandy beach is about 2-3 miles away, but it is quite nice. And the property has chairs and a cooler that makes trips to the beach easier.
We did have some trouble with the Internet. On a few of the days, it went in an out intermittently. However, this is probably not unique to this property. The property manager said that this is an issue with the local Internet service provider.
Overall, I would definitely recommend this place.
