We were disappointed that construction on the building meant that the windows and balcony opening were covered with opaque plastic sheeting, preventing airflow and a view to the outside. There was work being done on the building all day, including drilling into the walls of the building just outside our apartment.
Having said that, once the work is completed, the apartment is in a fantastic location, close to everything in San Sebastian: the beach, the newer side of town and the old town. Being in the center of town, there will obviously be some street noise, but it's a good tradeoff for the location.
The apartment itself was well appointed and very clean. The bed was comfortable. The check in was automated and once we figured out the automatic locks, going in and out was easy.
I would stay in this apartment again if there was no work being done on the building.
