I really couldn't be more enthusiastic about this hotel. Beautiful setting, wonderful staff, even the restaurant is good. Our bungalow had a waterfall shower! The heated swimming pool has a swim-up bar! There are beautiful flowers, butterflies and hummingbirds all over the grounds! The restaurant is open air, with views of the volcano! The rooms are huge (we got one with two beds), comfortable, and air-conditioned. We had a private jacuzzi tub on our back porch! And all of this for an incredibly reasonable price (I think around $150/night).
This place is off the main road, a couple miles from the town of La Fortuna, so if you don't have a car, getting into town might be a little tricky, but honestly, La Fortuna isn't a particularly interesting town, so you wouldn't be missing much. The front desk will book any tours you want to go on (hiking, ziplining, hanging bridges, etc), and you will get picked up at the hotel, so that is very convenient. (However, if you do have a car, I recommend doing these activities yourself - at much reduced prices - rather than these tours.)
But back to the hotel. . .honestly, if I could go back there tomorrow just for the pleasure of the Mountain Paradise, I totally would. I can't recommend this place highly enough.
