I cannot endorse this place enough. A complete garden of Eden ideal for families and couples alike. A bit difficult to find as it isn't on GPS yet but is signposted from the main road in La Fortuna and as long as you navigate to 'Z Trece' or Cerro Chato Eco Lodge then take the right hand fork in the road and you will find it on your right.
There, there is paradise and it is well worth the journey. Your private lodge is spacious for the price and immaculately clean, two queen beds, bunk beds and a superb bathroom. Top half is constructed primarily of wood with high ceilings.
Onsite there is a kitchen and eating area next to a small pool. A garden of Eden that has many types of orchids, fruit, ylang ylang tree (smells delicious at night) that you can walk around and enjoy.
You have your own hammock and AC in each lodge, some lodges have fridge, if you want one make sure you ask for it.
The morning greets you with a stunningly perfect view of Arenal, in a private garden of paradise.
Down side? Few, I would ask for extra towels in the room, that's it!
