We had a great experience at Marie and Simons beautiful home! It's in a decent location, close to Gare du Nord which we found ourselves using quite often, and there's plenty of restaurants, bars, and stores around. It was very cozy and just enough space for 3 adults. The bedrooms are lovely, with skylights that can be opened or covered by shades. The other windows also have electric shades that are great so it's not too hot or bright in the mornings. There was espresso for us in the mornings and great wifi. If you dislike stairs or are incapable of going up flights of stairs, you may have a problem, and the train does run behind the house, but we didn't find that to be an issue. The neighbors are so quiet that we didn't hear another person while in the building the entire time (6 days). We had no complaints about Marie and Simons home and would consider it again!
