We have stayed at many privately owned vacation properties but M Carmen's is tops on the list. She was seamless in our check-in, so helpful in tips for around San Sebastian and she went the extra mile in offering extra hospitalities for us. Her apartment is spectacular and the terrace with the kitchen is phenomenal. And the location was amazing. We literally walked everywhere from the beach, to the shopping to the pintxos. If you are looking for a stay in San Sebastian please don't pass this up.
