my good friend is french basque with some family still there. they are from saint martin de arrossa and stayed at:
hotel eskualduna chez katina and another place in saint jean pied de port
look on booking.com for many small villages (saint martin de arrossa, saint etienne de baigorry, saint jean de port)
many family owned "houses" with some having restaurants below, pools, garden views, on their farmland.

look at all the small villages around the countrysides (esplette, ascain, ainhoa, itxassou, osses, cambo les bains, saint jean pied de port: monday farmers market day) which are known for certain things worth looking at.
