Overall the stay was nice; however, be sure to clarify your reservation prior to arrival. The booking through TripAdvisor listed the property as a "3 BR/1 bath sleeps 5". I e-mailed that my 2 kids and I would be staying at the property. When we arrived, Haydee thought we had a party of 2 and the accommodations were a single room (2 beds) with attached bathroom. I'm not sure where the mix-up occurred, but if we had planned a larger group based on the advertised size, it could have been cramped.
The room actually was perfect for our needs (simple, quiet, close to the reserves), and Haydee was very accommodating The room appeared to be a converted family room (~20' x 20' square) with 2 full beds and a fold-out couch, attached to the main house. Breakfast was in the main house kitchen. Haydee was very patient as I practiced my Spanish, occasionally chiming in with English to keep the conversation going.
The property is very well located, an easy walk (albeit uphill back) to downtown Santa Elena's many restaurants (go to Taco Taco - it's awesome, and reasonably priced) and shops, a very short drive to both Monte Verde Reserve (the guides are great) and Santa Elena Reserve, as well as several other attractions that we did not visit.
My overall impression is very positive, but I would advise to email the property to verify the accommodations to ensure they match the listing.
