ah, quirky historic paris. apartment is centrally located in the 1st, in an ancient but well maintained building. apartment is on the fifth floor. must walk up one flight of stairs to reach the typically small retrofitted residential elevator. next door to chatelet-les halles entrance number 1 (place navarre). two-door entry to building (exterior door plus inside gated door), heavy front door to apartment, and the gardien (caretaker) made us feel secure. first bath has small sink, toilet, and shower. upstairs bath has sink, toilet, and narrow tub. fully equipped kitchen with dishwasher and euro/combo washer/dryer. smaller space upstairs has one large and one small skylight, so room didn't feel too small, even with double-sloping ceiling. nimbleness helps using the steep spiral stairs to the upper level. a couple of small grocery stores, boulangeries, and pharmacies close by. communication with eric was always quick. after check-in we didn't need to ask him anything because either he had explained what we needed to know or it was intuitive. just one key was provided, but that worked ok for us. bon journée.
