When we arives after 12 hours of sitting in a bus we had to wait an hour before the owner came. He told us the hostel was full booked (eventhough we had booked) so he arranged an other hostel and told us to make it up to us the next morning. The next morning he took us on a crocodile tour, gave us a spacious room with free ac and he made a nice price for us.
After the 2 day corcovado tour we went back to his hostel and they gave us another (spacious) but less nice room. The room was moist, could use some paint and the light didn't work...

I spent two night at Oro Verde Hostel.
For this price I got everything I needed. A comfortable clean bed in a shared room for 4 persons.
All rooms had sufficient fans so at night the heat was no issue which I highly appreciated.
The Hostel owner Juan is very friendly and helpful. If you have any issue, he will help you. I had several (cell phone broke down so no alarm clock, no universal charger, he let me use his computer).

All in all, a nice place to stay. There were 5 people staying in the room I was in, and all of us thought that the location was perfect, rooms were relatively clean and prices were really good. The owner who went by the name of simply 'jan' was absolutely incredible. Took us to feed Crocodiles and Caymans and even went out in the dark to see florescent Plankton. The only bad part about this hostel is that the room we were in (room 5) had a rancid smell coming from the small bathroom we had in the room. It was a very horrible smell and made just walking around in the room difficult. However, the other rooms that friends stayed in smelt absolutely fine. All in all, good hostel.
