My mom and I stayed here on a recent weekend trip to La Fortuna and really enjoyed it. The cabins are rustic but cute and great for the location. It definitely has a rustic feel, nothing fancy but comfortable with a kitchen, warm water. In my opinion, there is so much to see and do that you won't find yourself sitting in your cabin all day.
The hosts are really great. Jonathan who works on the property is EXTREMELY knowledgeable and will give you all great tips and suggestions for things to do in La Fortuna, especially if you are looking to stay away from the large tours.
One thing to keep in mind, is that it's about a 5-7 min drive into town.
