Had a wonderful stay at Carolina's place. We came to surf and the location was just perfect: right on the beach, lovely restaurants and the old city very nearby. The apartment was big enough for us 4, clean, well furnished (basic, IKEA, small but well equiped kitchen, large towels, large empty closets). There is a nice terrace with sun in the afternoon/evening. Carolina welcomed us at the entrance and gave us very useful tips about restaurants, surfing and parking. Overall a great place to enjoy San Sebastian.
