The first thing that I want to say is that Chris, the concierge is excellent- we felt like we had the best guide in Costa Rica. He is very good at communication and execution of plans, and he is even better at doing tours. We did a thermal pool tour and a waterfall tour , and both were gorgeous, informative, intimate and sweet. He personifies "pura vida" in his genuine excitement for sharing his country and its natural wonders. I feel very fortunate to have spent several days with Chris as our guide.
This house is amazing, and while I have a few minor complaints, overall it was almost perfect. The pools is really lovely- very clean, good size, perfect temperature. As a swimmer, it was a 10. The main living room is gorgeous, as is the main bedroom on that floor. The dining area and deck on that floor are also great. We had 11 people there and felt very comfortable. The one complaint is that the kitchen is not set up very well for real cooking. The pots and pans are small and cheap teflon- it made cooking difficult. This is not unusual for a VRBO, but it kept the overall experience from being a 10.
The remainder of the living spaces were fine- not super special, but very nice. Several of the baths were pretty spectacular. A sign on the deck stating a 500 lb limit was a bit unnerving, sice you are 40 feet from the ground, but we assume it was a liability thing, not a real problem.
The location of the house is pretty perfect, and one could do without a car there, if you are healthy and can walk up the steep hill to the store, and downhill to the beach.
The maid service was also excellent.
Overall I can heartily recommend, Casa Diamante!
