The best area to stay in Ainsa is the old town, known locally as "Casco Antiguo," which sits atop a hill overlooking the modern town and the surrounding valleys.This historic quarter is the main attraction, characterised by its cobbled streets, mediaeval architecture, and the impressive Plaza Mayor, a large, arcaded square that serves as the heart of the area. You'll find many of Ainsa's best restaurants and artisan shops located within these ancient walls.Couples often find the old town particularly appealing. Its romantic setting, with panoramic views of the Cinca and Ara rivers converging below, is superb for evening strolls and intimate dinners. The castle ruins and the Santa María church add to the historic charm, providing a picturesque backdrop for a relaxing getaway.For those travelling with families, staying closer to the modern town centre, just below the old town, offers a bit more convenience.
