We enjoyed our all too short stay in Olivier's beautifully located apartment in the Marais. The accommodation was comfortable, & our hosts & their cute dog very welcoming. We had access to use the apartment as if we were in our own place. Only problem we could see was for older people to climb 4 floors, no lift. But Paris is a city where walking is essential to enjoy it, so for us it was worth staying at this apartment & meeting two charming hosts.
