Honestly, I'm not sure where to start. It was basically an abandoned old building on a lonely 4x4 mud road in upper Nosara. No reception or hostel staff there on a regular schedule, just random visits. Water in bathrooms and kitchen was not working. Mattresses were in terrible shape with dust, dirt, black mould. I know it's not easy to keep them in good shape in the humid air, and I'm used to rough sleeping, but this was bad. The walls had several larges holes as well for insects and other critters to get in. Two ceiling fans in working condition, but with possible mould on them too that seemed to have spread onto the top bunk mattresses.
With the very lonely setting, safety concerns as well. There are sometimes very few other guests (if any) and there is no staff on site overnight.
