Very centrally situated with lots of good eating places about, we particularly liked Okamika which we would highly recommend for the wine and food.
Getting bits and pieces from the car was not easy as only place you could stop was at the bus stop out front and the bus drivers were not at all happy. Clearer directions re getting to the local underground car park nearby would help to make life simpler. Was a very stressful experience for us.
Parking in Zarautz is a nightmare - there is done except for the underground just 100m away at 21€ a day, so factor into your daily budget.
