The apartment was very well located in the old town, although if you are carrying a lot of luggage, be aware you can only reach the apartment on foot, because it is in the pedestrian area, but only a few minutes walk in any direction that cars are allowed. Our taxi was able to take us as close as 300 metres from it.
The terrace is a great bonus. The apartment is very spacious and well equipped. Communication with the host was always easy and prompt.
It was our first time in San Sebastián but I am sure we will come back. I would be happy to stay in this apartment again.
