TL;DR: A simple base of operations in a superb location hosted by lovely people but with some liveable problems.
The good:
This studio has a well equipped kitchen (toaster oven, full stove, big fridge-freezer, could do with another chopping board and sharper knives) and is sensibly laid out.
The couple that own the place seem kind and respected our privacy.
The location is fantastic (rainforest with frog and birdcalls through the night) and is an easy drive to black sand beaches, restaurants and volcano activities.
We had an issue (listed A/C that wasn't there - you probably don't need it) that was resolved to our satisfaction.
The bad:
The bed is pretty uncomfortable and the whole place gets rather sticky and damp (no A/C and it's a rainforest).
The WiFi is essentially unusable. Maybe okay for an email or two, no good for TV or chat. There's limited cellphone reception.
The issues we had were resolved, but require lots of energy to work out (especially with limited comms). I did not enjoy my interactions with Evolve.
