Great location, in the middle of all the attractions and food - all within walking distance (1-3KM) if you’re willing to walk. Nearby supermarket (Monoprix) for necessities and train station (Chatelet Les Halles) were only 2 mins walk from the apartment.
Room itself is comfortable for a short stay (3-4 days), although the toilet is slightly small. Room is equipped with kettle, Nespresso machine and coffee was provided. Heating was adequate and worked well. You have to climb up 3 flights of stairs (which were a little steep) to get to the flat so it might be difficult for elderly / anyone with big luggage.
Emmanuel was very friendly, helpful and responsive. Allowed us to leave our luggage for additional 2 hours as we wanted to spend extra time out in Paris. Was also responsive when we changed our check-in timing.
