Carmen is the most warm-hearted, most considerate, most welcoming, knowledgeable and informative host imaginable. Open-water swims is my personal passion and she guided me to five different impossibly wonderful locations for that. But she also has expert guidance on museums, churches, bridges, shopping, theatre, language and all other aspects of Basque/ Spanish culture. Delicious breakfast every morning, delightful company, brilliant chef, she is now my 'ama euskaldùn'! I hope not only to return to her casa, but also to welcome her to my casa, in Dublin, Ireland. She is the AirBnb champion of Bilbao, no doubt!
