This property is fantastic! It is a very practical Studio apartment with a fully-equipped kitchen and bath. The beds fold down from the wall and are actually very comfortable. The balcony is furnished with a table and two chairs and looks over the Vieux Port, probably the nicest beach in Biarritz. One can look down the cote Basque on one side, viewing Spain on a clear day, and up the coast to the lighthouse of Biarritz on the other. The view is simply exceptional.
While the location is right on the ocean, it is easy walking distance to the city center. This area is popular with partiers and motorcyclists, so expect noise into the night. The property is thus excellent for those who want to enjoy the nightlife! Personally, I found it a bit too "animated" for my taste, and look forward to renting this property again during a quieter season (I was in Biarritz during the highest of the high season). In any case, the balcony doors were effective in keeping out the noise, so I had no trouble sleeping.
The apartment does not have wifi, although I was able to use a hotspot through my telecommunications company, SFR, so there was no problem. There is also a Biarritz city wifi for public use, although I did not test this.
All in all, I highly recommend this property! It's a great base to explore the Basque country, or to just relax on the balcony with a drink and take in the marvellous view.
