We had an absolutely brilliant stay at Gustavo's place. The apartment is charming and spacious, and the roof terrace enormous and sunny! The photographs didn't do the apartment justice; it's well appointed with loads of storage and huge sliding glass doors everywhere. The bathroom is small, but the power shower was a total bonus. The location is ideal - just on the edge of the old town and within easy walking distance to everything you want to see in San Sebastian. I'd recommend this place without hesitation.
