This was a good hostel. The staff was very helpful, they had internet, close to the bus, walkable to Quepos (take the bus to Manuel Antonio). We had 3 people in a 4 person room and it was very comfortable.
They also have real mattresses, not the pieces of foam that you find most places in Costa Rica. The only complaint would be that the rooms face the road and there are a lot of loud trucks rolling by at all hours of the day.
