Highly recommended. We stayed here in February/March 2012. The location is away from the city center and we always felt VERY safe. As, three young women travelling alone, this was important. The location is about 10-15 minutes on one main road out of the city center and 5-10 minutes on a gravel/dirt road. Use the map on the website to help find, since there is no address, and make sure you have the phone number, in case of trouble finding. Once you get there, you will realize chosing to stay here was the right decision. You immediately feel like part of a family. Jonathon is so welcoming and passionate about the natural surroundings. Cenyeca (pronounced Seneca) is the chef and cooks delicious, fresh, simply perfect meals for the guests. She made the best food we had in Costa Rica, by far. They gladly help you figure out plans for the area (ziplining, white water rafting) if you would like recommendations, and will even make calls for you to set everything up.
It is located in the middle of the forest, and there are many paths built so you can spend hours and hours walking the land and hiking, taking pictures. The "watchdogs" (best dogs ever) are so friendly and will accompany you on hikes if you'd like. You can even just sit on the porch and have a spectacular view of Arenal Volcano and the forest and do bird watching. The room was free of bugs and very large and comfortable. I cannot say enough about how great our stay was and will absolutely be back again. I am not exaggerating about my ratings. Everything was excellent, and our trip would not have been as great if we had not stayed here.
