We had been to San Sebastian before, and chose this Apartment based on the excellent reviews and the location.
Previous guests have said it all, but please pay attention to the following!
1. Communication & Check-In. Responsive, accurate and helpful. We felt confident from the moment of our booking, that we had a good owner.
2. Location. Simply the best. Two minutes from pintxo heaven, the old town, the market, and several coffee shops. One minute from the sea. And still far enough away from the crowds to be quiet and relaxing when you need a break.
3. The apartment. Spacious, extremely clean, and well equipped. All of the accessories and furnishings make it feel like home. If you have a car, the car parking space is a huge bonus.
Summary: You may find cheaper, but you won't find better. Just do it.
