I have stayed there before it was acquired by Hyatt. It is a beautiful property with luscious landscaping. It was formerly known as Casa de Lourdes for their restaurant on the main building. We stayed in one of the casitas on a second story and a cute balcony.
There is a lot to do and explore while in el Valle, so this is a great addition to their portfolio that can be booked now with WoH.
While in El Valle, you can zip line, hike India dormida, shop at local market, go to thermal mud baths (and take some home).
