Will definitely stay here again. Location is amazing, right in the 3rd arrondissement. Metro stop right outside, major train station just three blocks away. Many areas around are pedestrian zones with many cute cafes and restaurants, so it's really fun to explore. Tons of good food nearby and so many cute local shops around. Lots of fun gay bars around too. Place is super cute, cozy and mostly quiet and peaceful (on Friday night I slept with the window open and heard some noise from some loud folks coming out of a bar, but other nights were totally fine.) Very clean. Pierre-Alexis was great. He was available to answer questions and was extremely responsive. There were towels and thoughtful pouches if soap to use (although I had brought my own). There are all the kitchen appliances you could need, but if you're staying in Paris you should never eat at home. Go explore!
Notre Dame is a 15 minute walk.
Bed is a pull-out, but was comfortable enough. Entire place is newly renovated and modern.
