Skip the hustle and bustle in Donastia-San Sebastian and stay here. Ramon is an amazing host, with an amazing apartment in an amazing place. Ramon and his lovely wife greeted my family of four, helped us carry bags up to the apartment, and gave us tons of tips for our stay. Ramon left us milk, coffee, yogurt, cirdral (a traditional Basque drink), bread, and eggs. What a thoughtful touch! The apartment has been in his family for a long time and it's wonderfully clean and decorated. Ramon did some of the renovations himself. The furniture is "upcycled" from his family and from area farms. It's really cool. The appliances are new and work well.
Ramon was available to answer questions throughout our stay. He even helped us find babysitters. If there were a Nobel Price for AirBB hosts, Ramon would win!
Asteasu is more than charming. It's a very small town and you are likely to be the only tourists there. We loved that. We met locals and the bar across the street, and even ventured out with them to a Basque sing-a-long in the next town. Asteasu features two bars; a restaurant; a small, but well-stocked grocery store; and a fruit stand. All of these places are within a 1-minute walk. The restaurant is directly across the street from Ramon's place, and the food is fabulous; the best we had in Basque country (just check the google reviews). Ramon's place is a perfect location from which to explore the Basque country. We debated staying in Donastia-San Sebastian, and we are glad we decided not to. There are lots of tourists there and it's a lot more expensive. We rented a car and explored the beaches and wonderful towns in the Basque country (we loved the beach in Zarautz). Our only regret is that we didn't stay longer!
