Location of the house was wonderful - right next to a great beach and a short walk from the main bus into town. We didn't see an easy place to buy coffee/pastries nearby, but got used to taking the shuttle a few stops into Biarritz proper.
Pierre was a great host, offering to lend us a surfboard if we wanted, grabbing an extra towel for us when I asked, and even offering to give us a lift to the train station. We really appreciated his kindness!
Otherwise, the space in the rental was very cozy - really just one room with the small bathroom and kitchenette. There was a small table on the porch where we spent most of our time. The rental was mostly empty - we bought shampoo and a few basics once we realized. Wifi signal wasn't very strong. Good time overall!
