Great location, great apartment. Go to the tourist office for a map and informtion. The Basque Museum is amazing and free on a Thursday evening. We did a tours of Bayonne ham making for 5 euros. The transport is amazing with free little bus around the town but also an amazing tram/bus system out to Anglet and Biarritz 2 euros for 24 hours. We took no 38 to the mouth of the river, walked along the coast (about 8km) to Biarritz in the sunshine and then a T2 back to Bayonne. Super day! Enjoy your trip.
