We were four and spent three dreamy days in the apartment.
Adele and her brother (Armin) were really friendly and nice, during the delivery of apartment Armin introduced the different parts of Paris and answered our questions very patiently. he were flexible for us at check in and check out time.
Apartments were very clean and lovely and the kitchen well equipped.
Bicycle station were very close to building (30 second) and we went around by bicycle every day, although only five minute walk you can arrive to Eiffle.
