We stayed for a week in St Jean De Luz and loved Mercedes's apartment. It was bright, spacious and in a great location, literally just off the beach and maybe five minutes from the main street in the town. It had everything we could have wanted and was a great place to chill out after a day of sight seeing or baking on the beach. My only word of caution is that if you are hiring a car, free parking is hard to come by in St Jean De Luz and we thought the paid parking was really pricey, there is paid parking right next to the apartment but it costs nineteen euros per day!!
