I stayed at Emmanuelle's apartment for 6 weeks remote working, and everything about the apartment - location, setup, cleanliness - was top notch. Emmanuelle went above and beyond with her thoughtfulness on welcoming me to Paris, and was very easy to communicate and work with when I asked to host a visitor during my stay. Emmanuelle provided plenty of towels, 2 sets of bedding and as there was a fully functioning washer/dryer in unit, I could regularly switch the linens out for cleaning.
If you plan to do any remote working or studying, this is a great apartment - there was a table in the living area, and a desk in the bedroom. WiFi was strong the entire stay, never had any glitches, and there were plenty of extension cords for my equipment.
I was pleasantly surprised at the roominess of the apartment - I had been warned that Paris apartments are tiny - and felt like I had more than enough space even when I was inside 8+ hours working.
The location is excellent for visiting - tons of restaurants and shops around the corner and in very easy walking distance of the Metro and museums. Laduree is down the street for afternoon tea and macarons, Les Deux Magots is 3 blocks away for a perfect French breakfast, and Cafe Flor just one block past that for Paris' best late night hot chocolate.
One note, the apartment is on the top floor up 4 flights of stairs - no elevator; and the bedroom is separated from the living room by another flight of stairs. So when you're coming back from shopping after stuffing yourself with croissants, pace yourself going up.
