Christian’s place is well located, within walking distance to many Montmarte landmarks (Sacre Coeur). The apartment is a clean, well equipped, bright studio apartment on the top floor (5th) of a bldg but with access to elevator - a definite perk especially in Paris. I stayed in Christian’s place for 2 weeks and was living comfortably. Wifi was good, kitchen is well equipped and there is a washer in the unit and you have your own private balcony so fantastic for an extended stay.
Christian is a fantastic host, very responsive to any questions you may have! In one instance, when the temperatures dropped at night I casually checked in if there is heating in the unit, Christian quickly informed me that the bldg is in central heating. Since that wasn’t turned on yet, he immediately arranged for a portable heater to be sent to the apartment.
I would definitely recommend Christian’s place for either short or long stay and I won’t hesitate to come back.
PS. The apartment is right next to a grocery store - super convenient. Additionally, several boulangeries, brasseries, restaurants (incl. a Michelin restaurant) are within (5-10 mins) walking distance to the apartment.
