We are walking from 15th Sept - 23rd Sept (can't wait!) and need to store one suitcase in Biarritz /Bayonne but we are not staying the night there, either coming or going ( brother to meet in Toulouse so no time for extra sleeps). Does anyone know anywhere we can find 8 days storage of one piece of baggage in Bayonne /Biarritz? Happy to pay something reasonable - just can't stay the night.
