Recently stayed at the Blue Jay Lodge during the peak season in Santa Teresa. Our visit was a bit of a mixed bag, we felt there were several things we were not aware of when we arrived.
Pro's: nice lobby area and pool, very comfortable to hang out in during the day. Breakfast provided is simple but nice, and apparently there is sometimes ceviche in the afternoon. David is very friendly and helpful to guests. The view of the ocean from our casita was stunning.
Cons: We stayed in the Congo room, which was essentially a treehouse. Way way way up the mountain, it has slatted walls with netting, that's it. The building/room is slanted downwards and the rails on the balcony are ropes strung on a pole. The accommodations are absolutely bare minimum. The shower barely had a stream, mattresses were cheap and rickety, several large gaps in the screen between the wall where large critters or animals could come in. For the price we paid this was "roughing-it" much more than we were prepared for. Also one morning our water was shut off. And the wifi is only in the lobby, does not extend to the casitas. The location is not as close to town as we thought either, nearly a mile down the road. There are bikes to rent that help but they are not in the best condition and make for an "interesting" ride.
Overall I give this a so-so rating, I wouldn't recommend against staying here but if we had known some of the above we probably would have stayed elsewhere for the $$ we spent.
