The apartment is close to many shops, restaurants and the beach. No need for a car. The kitchen was well equipped. I worked there for 2 days and the internet was great.
Although the livingroom and one bedroom are on the boulevard-side, the windows provide a great insulation. Can be noisy when the windows are opened though. The checkout is at 10am, as specified in the listing, but apparently there's no room for negotiation (that was it experience at least).
Special mention to the beds that were really comfortable. Overall, we had a confortable stay and it's a central place to visit Hendaye on foot.
