Jean-Pierre's flat is located in a quiet neighborhood that's walking distance from the city centre and the beach (10-15min).
We were welcomed by Valerie who showed us the flat and gave nice tips on beaches, food, market etc.
The flat itself is a one bedroom apartment with a small garden (as accurately mentioned in the description). Or toddler especially enjoyed the garden and the space was great for the three of us.
There's a beach umbrella, mat, body boards and beach toys for the kids which is very convenient.
We traveled to biarritz by train and there's a bus stop at 100m from the flat which is very useful. It's right next to a casino supermarket.
Overall, a great stay and would definitely stay there on our next trip to biarritz!
