Guest Apartment Services lived up to all they had presented. The apartment "Callas" was what we had hoped, comfortable and with rustic parisian appeal. Location was phenomenal, we never got tired of walking by Seine each day under the blue sky, then coming back to our apartment at night with Seine & Notre Dame under illuminating lights of Paris, it made our trip that much more memorable. Merci Beaucoup to Christophe, Phillipe and entire staff at G.A.S.
