Arenal Hostel Resort is, in my opinion, the best hostel in Costa Rica. The staff is extremely helpful, nice, and friendly and the rooms and common areas are kept impeccably clean and beautiful. My friend and I stayed here for five nights and Alonso and Jennifer were so helpful in helping us plan tours, answering our questions, and giving us advice about things to do in La Fortuna. We stayed in the all women six person dorm and it was such a great experience. I highly recommend this hostel as well as visiting La Fortuna/Arenal. AMAZING!!
