If you are looking for a calm, enjoyable time in Santa Teresa, then stay here!
When I first arrived to Santa Teresa I stayed at another hostel, but one night and I knew I needed to find another place. I was in Santa Teresa at the end of August, which is the beginning of low season in Costa Rica, so there were not many people in town. I walked to a number of different hostels to look at the facilities, but didn't find one that I thought I would like for the few days I would be there, then I remembered that my friends had raved about this hostel in Santa Teresa called Casa Zen, and once I saw it I understood. There are other hostels that are cheaper in town, but the dorm rooms are nice and if you are travelling with 2 people the privates are the same price as staying in a dorm and that is a great deal. I loved the balcony with all the hanging hammocks and spent a lot of time there. It is only a 2 min walk to the beach from the hostel. The owner is great, myself and another guest had some issues on the beach and the owner was very helpful and compassionate. There is also a restaurant downstairs that has great food. In the mornings for an additional charge you can do yoga, and the instructor is amazing! She was so helpful and knowledgeable, probably the best instructor I have worked with. I had a great time here and will return again!
