Cute little place just down the road from Gare de Lyon. We only stayed one night, but the staff was pleasant, the room was small, but clean and quiet, the shower was excellent (enough water pressure even in the upper floors, which is not that common in old buildings), and you’ll find the little “bistrot” for your typical french breakfast right on the way to the next Metro station (I never book breakfast, it’s mostly not worth the money and you will find much better food and a more unique atmosphere outside of your hotel, especially in Paris). IMHO the perfect place to stay, as you are not going to spend much time in your room anyway, apart from sleeping and showering.
