We traveled in Oct 2013 with a group of 10 to StJ. After looking at several properties, I decided on Casa Luna and I could not have been happier with the villa. There are 5 bedrooms on 2 levels, 2 kitchens, 4 bathrooms, pool, hot tub, screened in porch, and decking wraps completely around both levels of the house. We never felt crowded. The management company was easy to work with and very professional.
The views from this house are AMAZING! The backside of the house overlooks Leinster Bay and Tortola. In my opinion, it is the best view on the island. We would definitely stay here again if we went with a large group.
