Stayed at Casa Bellavista for 3 nights. It's situated in the Candelaria area beside a square with some bars and restaurants.
We had a great stay here. The family who run this small hostel are extremely attentive and caring hosts. It felt more like a home than a hostel. They arranged an airport pick-up for us.
They were extremely helpful when we were looking for restaurants and in booking tours for us.
The breakfast each morning was excellent. Eggs, bread, coffee, tea and the hot chocolate gets a special mention.
I would highly recommend this hostel.
