Nice and very comfortable apartment, in a fantastic location. The bed was very comfortable and it was a bonus to have a very nice shower and washing machine.
The WiFi was reasonable for working, although did drop out now and then. The internal balcony looks out on other apartments, we didn't use it. However it's quite close to the beach and we didn't really need an outdoor area for the apartment.
The staff were contactable for any questions.
Would definitely stay again when returning to San Sebastian! 🙂
