We loved this Airbnb located in the center of old town. It is close to Le Grand Plage and the other beaches, shops, markets, restaurants, cinema, and the historic church.
The south/west facing apartment on the third floor is new, modern and comfortable, with a washing machine, dishwasher and a great bathtub.
Two French doors that open to patio's allow for a lot of natural light and views of Biarritz.
Communication with Maria was excellent. She was a helpful host.
