Fantastic place to stay
What a fab hotel!! There are 6 bungalows off a paved path, surrounded by jungle, and far enough apart that you don't really see anyone else when you're in yours. There are also 4 suites in the main building that also houses the open air restaurant. We had a family bungalow at the end of the path. It was really nifty, and had 2 floors. You entered into the upstairs, that had a king bed, 2 bedside tables, a full bathroom, desk and chair, 2 rocking chairs, a bench, and a little kitchenette (mini-fridge, hot water carafe, sink, counter space). Off to the side were the stairs down to another room with a king bed, 2 bedside tables, and full bathroom. There wasn't much furniture in the downstairs room and that was maybe the one thing I think could've been better (add a table and chairs, etc). Both had big windows and sliding glass doors, with the forest right there. We saw some interesting birds, agouti, and a coati climbing trees while standing on the balcony. It's quiet, private, and lovely. The staff there is top notch. Super friendly, welcoming, and accommodating, and they remember everyone's names, and make a point of addressing you (which I found impressive because I have a miserable time remembering names). The included breakfast was wonderful. You order from a menu, with stuff like gallo pinto, waffles, etc, and it came with a fruit plate and juice. It was excellent every day. The restaurant has an expansive view out over the trees, and on a clear day you can see the ocean (we did get to see it one day). We ate dinner there one night and it was very good. Great hotel!!
As for critters, the staff pointed out a mama and baby sloth in a tree nearby one morning, and another lone sloth a different time. :) We saw a massive black snake in the road on the drive up the first day (convincing me that we wouldn't walk to town ar ar). The afternoon we arrived, a pack of coatis moved through the area by the hotel, with mamas and babies digging around for stuff to eat, and jumping here and there. I would say the odds of seeing critters there is very high. :)
A super cool thing about the Koora is that it's right next to the Aguti reserve, owned by the hotel, and guests can come and go as they please, whenever they please. We were over there everyday at some point. If you go there, be sure and take a picture of the map before you head in. Hub had scanned the hotel's QR code and a map of the reserve was one of the things on it, so fortunately we had that. The first time we went in was the afternoon we arrived, and we figured we'd just go explore for an hour and be back well before dark. We got so turned around! I was a bit worried. The signs along the trails aren't 100% clear and there are no maps along the way. Finally figured out we just needed to head down and finally got out. The next time I looked over the map beforehand, and that certainly helped. :) We spent a fair amount of time in there and saw agoutis, coatis, wild turkeys (we think), howler monkeys, leaf cutter ants, etc. It's a great little reserve and we rarely saw anyone else there. Huge plus to staying at the Koora. :)
