We had an excellent stay at this Westin studio/loft--two adults, two kids. The owner, Mitchell, went above and beyond with the booking and arrival process--even provided some recommendations for food, sights, etc.
The unit was as advertised, and served as a great home base for our family to explore the island. It's located across the street from the main resort pool area (easily walkable, or catch a ride in a golf cart from Westin staff), but also has a smaller pool area of its own. The location is a 5 minute drive to Cruz Bay restaurants, and if you rent a car you can park right outside the villa.
Westin staff was prompt and professional with any needs. Would stay here again.
