Great place in perfect location. This apartment is located in the heart of San Sebastian's old town. Within a five minute walk are at least 100 restaurants (I'm not exaggerating). Besides the many restaurants are an amazing array of food stores and the huge meat and fish market is underground just across the street.
Susana was a great host and responded to every request in minutes. She messaged us almost every day to make sure everything was OK and even went ahead and booked a reservation for us because she knew restaurants would be crowded and wanted to make sure we didn't miss out.
The apartment is on the 6th floor and has an elevator for easy access. It's very clean and comfortable and the terrace is huge with a nice view of the river and beach. The water is even closer than the pictures indicate. Even in November, we were able to use the terrace most day.
I highly recommend Susana's place.
