An ideal location, close to Gros and the Old Town. It is especially handy for the main bus (and train) station which is great if you fly in to Bilbao. Sometimes the areas around bus/ train stations are a little intimidating, but not here. the whole area was really nice.
Mariaje was very helpful when we needed it, and was very flexible about arrival and departing. I would recommend it as a place to stay in San Sebastian.
