This is an amazing house with 8 bedrooms each with its own bath. One of the best features is the outdoor entertainment area. There is a beautiful pool, Jacuzzi, bar and seating area with a view of Lake Arenal. There is a bar/restaurant very nearby which has a limited menu.
The management went above and beyond to accommodate us and were easy to work with and very responsive.
The only down fall is the poor road quality of El Castillo. However this is a necessary evil if you plan to go to Sky Tram/zipline or the trails around Arenal Observatory Lodge which is nearby.
