This is the perfect location with epic views of Biarritz, extremely comfortable and all the comforts of home (modern kitchen, washer and dryer, great/modern TV and WiFI).
Both sides of the apartment look up and down the Basque coast--if you open the sliders the sea breezes are amazing and the views are spectacular.
The beds are very comfortable, great sheets and pillows. My son and I stayed here and slept soundly every night with the sea air and comfortable surroundings.
You can walk to pretty much everything in Biarritz from the central/coastal location, so you really don't need a rental car unless you're planning to explore the coast.
Strong recommend. We will be back!!!
