We spent two weeks at the end of June in the Azalee apartment across the street form the Les Invalides.  From the beginning of booking to the end of our stay, the staff at Guest Apartment Services was superb.    They answered emails within the same day that I sent them (which was great given the time difference between France and the US) and provided me with all the necessary information that we needed.   They arranged for a driver to get us at the airport and take us to the apartment.   We arrived on Saturday when the office was closed but Marie met us at the apartment within one hour of our arrival to explain everything.    The apartment was very clean and equipped with everything that we needed.  The apartment was cleaned and linens replenished twice during our stay at no additional cost.   Overall our experience with Guest Apartment Services was fantastic!  I would highly recommend them to anyone. Their attention to detail and professionalism is exceptional!
