We have stayed at my maison invalides before our stays at my maison louvre. Both location are good, depends on what main attraction you are looking for. Apartment in Louvre is smaller than the invalides one. There are few restaurants directly below Louvre apartment, which creates noises in early morning (moving tables and preparations) and late evening (people at restaurants). Overall it is a nice design apartment in a great location. Within walking distance to Louvre, Vendome, Ile de la cite, ile saint louis, shops at rue saint honore
