We stayed here also for 2 nights as part of our explore tour.
We were in the highest block up the hill rooms were spacious and very clean ( yes we had to walk down the hill but really?), view was magnificent, breakfast was tasty.
As for insects we saw a few but none in our room but if we had it would have been the 'Adventure' in adventure travel presumably the reason why most people come to Costa Rica!
We stayed in 7 different hotels and this was hands down our favourite.
