Located in the historic center of Saint-Jean-de-Luz, this residence known as the "Maison de l'infante" was built in 1640 by shipowner Joano Harraneder. It was inhabited by the infanta Maria Theresa of Spain during the period leading up to her marriage to the French king Louis XIV.

This listed building is a 4-storey mixed commercial and residential building set in 359 m² of grounds. This exceptional building is located in the city's best location.

On the first floor, there's a 162 m² commercial space (excluding storerooms) divided into 3 lots, as well as storerooms and 62 m² of common areas.

The residential floors are in average condition. On the 1st floor is the infanta's 243 m² apartment. The 2nd floor comprises two apartments, 202 m² and 47 m². The 3rd floor offers two apartments of 112 sq. m. and 115 sq. m. with attic space and tower.

The singular character of the premises makes it possible to envisage a quality layout for 5 or 6 apartments, if the current distribution is modified and an elevator integrated. It should be borne in mind that the building is partly blind on two sides. There is a risk that 1/3 of the surface area will be depreciated by around 20% in terms of m².
