We (2 parents and a 3 years old daughter) spent four nights at Pierre and Katy's place in Biarritz. We enjoyed stylish interior of the apartment. All the equipment and furniture inside were NEW. Parking slot in the garage was big enough to fit a compact SUV.
There is a stop of a free shuttle bus 30 meters across the bulding - very convenient way to get to/from main places of interest in the city. On foot, it takes approx. 20 minutes of relaxed walking to the beaches.
There is a supermarket (Casino) 10 minutes walking from the apartment.
In the mornings it may be a bit noisy from the street especially if the windows are open, and you are sensitive to street noise. But that is common in Biarritz. Not a major concern.
We definitely recommend Pierre and Katy's place and would love to stay there again.
