A fantastic apartment in a location great for walking and public transit, with beautiful views of Sacre-Coeur (especially at sunset)! I stayed 3 nights, using it as a base for a work/tourism combination trip, and it was perfect for me as a solo travel. It could fit more but might be a little tight. The lofted sleeping area was kept comfortable during a very hot couple of days thanks to a fan, a window, and a remote-operated skylight that allowed for cooling cross-breezes. The top floor location allowed for the excellent views and the breeziness, but if you have trouble with a lot of stairs or need to bring in multiple heavy suitcases it could be difficult. However, if you travel lightly and don't mind a climb, your reward is a beautiful little studio with plenty of space, a nice kitchenette (kindly stocked with tea/coffee), a nice bathroom and shower, and wifi that worked well when I needed to get online for work. Plus, the hosts were very responsive and helpful. The in-unit washing machine was a lifesaver that allowed me to pack much lighter, as I stayed there halfway through a multi-city trip. And everything you need is available within just a block or two of the place -- restaurants, grocery stores, bars, cafes, pharmacies, bakeries, even a nice record store. And it's less than 10 minutes to walk to Gare du Nord. Overall, highly recommended!
