Apartment is very clean and in a good location. Short walk from the old town and beaches. Good value considering how expensive other apartments are in San Sebastián.
A few minor downsides, the apartment doesn’t have A/C, which we knew however when travelling in the summer be aware that it does get very hot. A fan is provided. There was also no ironing board. When arriving you have to pick up the keys from the office which is 1.5km away from the apartment. When travelling with bags and walking in the heat it’s quite an inconvenience.
Despite these minor issues we would definitely recommend.
