We had a very nice trip to Bayonne, a pretty town on the river with many nice cafes & restaurants.
Joanas apartment is in a very good location, very central, with everything you could need. It was very nice to have a fresh coffee machine and the terrace is a nice place to sit (unfortunately we had a lot of rain on our trip so couldn't enjoy it as much as we'd hoped!)
We recommend getting a 7 day bus pass for €11 which means you can visit other towns such as Biarritz within easy 30 minute journey. Also the airport is an easy 25 minute bus to Bayonne on number 14.
