Renting a car and driving through San Sebastian is one alternative of getting around the city. Having your own car makes your tour more private and you can visit the sites at your own pace.
As for parking, street parking spaces are usually available outside the Old Quarter. Be sure to follow local traffic and parking rules. In addition, take special note of where you park. If you don't park in designated parking areas, your car is liable to be towed. There are many underground parking spaces available throughout the city.
