Staying at Casa Garcia-Mar is a great experience. The property has a wonderful terrace with views over the Atlantic; lovely seating areas; and, a swimming pool. Inside it is cosy and clean.
If you want to explore the Teguia volcano, this is a great base; you can walk from the house. Be aware that some of the walking, particularly when hot, is quite difficult - make sure you have lots of sun protection! You can travel to Los Canerios easily for provisions.
Luis is friendly and helpful and meets you at the property. If you need anything, he is easy to contact. Even though the property doesn’t have WiFi, the signal is good for your own data.
I recommend staying here as a good base for the rugged south of La Palma.
