We had a great stay in San Sebastián and Mentxu was a fantastic host. The place was in great condition and very comfortable. It was in a quiet neighborhood and easy to access. The place was a bit larger than what we needed, but still a good price.
It is only a short walk from town. It is perfect if you’re looking to wonder around town. The only problem is if it is raining. Make sure to download the local taxi app as they don’t allow uber in Spain at the moment.
