This was not the apartment we booked to stay in. The apartment we booked flooded just before our arrival and the Rentals Collection agency promptly moved us to another apartment in the same area.
This was great service and it was great that the apartment was so central. The location was ideal, within easy walking distance of both beaches and the old town with the best pinxtos bars.
There was nothing wrong with apartment itself, it looks exactly like the photos. But it isn't very homely or as cosy as the place we booked originally. It is obvious that the apartment is rented out and that it is not lived in.
The only other thing to note is that parking in this area is difficult as much of the old town is pedestrianised. The underground car parks are expensive. And you have to collect keys from about 10 minutes away, although they make it accessible if you arrive outside of office hours.
San Sebastián itself is wonderful and I would highly recommend visiting here!
