We spent 11 nights at the property over Christmas and it was perfect. Christine and Tom are the most gracious hosts.
The house was immaculately clean when we arrived. Everything you might need is there and more - and in perfect working order and condition. I cannot stress this enough, we're in the jungle but everything looks brand new. Also we litterally didn't hear a sound from the neighbouring houses (hidden in the vegetation) in 10 days, like we were alone on top of the world.
We used the outdoor grill everyday. The children loved the Sonos system and the dozens of movies on Plex which we would watch in the hottest hours of the day.
And of course they loved the pool (which has a nice lighting system at night and is quite large with sun or shade, whatever pleases you) and spending time in the outdoor area, reading in the sitting hammock, on the couches or the deck chairs. It is a nice touch that the house provides a scope to look at all the birds which dance around the house before 6am. There's also a convenient outdoor shower (again, this house is very sophisticated in all that's been thought out for the guests' enjoyment).
With the amazing view and the colours and all the classy materials used for the house (the different woods! the nice bathrooms and half-bath!), you're bathed in beauty from the moment you open your eyes in the morning. The king bed in the master is excellent. The air conditioning works like a charm in every room. You may find larger houses but they might be more expensive and less elegant.
Sidenote on the activities
We booked 4 tours through Karol at Pacific Expeditions. Our favorite was the rafting, done by Dominical Surf Adventures, it was great. The ATV tour and the rafting tour take pictures, they can give them to you through Airdrop, Whatsapp or at the rafting place, plug in your Android to their laptop. Unfortunately the tours actually provided by Pacific (snorkeling and Corcovado) did not have good guides. Those folks didn't make it a fun experience (such a pity as Karol herself is super nice and responsive).
We also did the Nauyacas waterfall with their 4×4 economical tour at 7am, it was magnificent. If you want to rent a car, plan ahead as they go fast in the peak season. Adobe has an agency in Uvita now. Should come around eighty-ninety per day.
