We would definitely stay here again. The building felt secure as you had to use a code to get into the building, then a keycard for the next door, then a key to the door to the apartment. Quiet building. Didn't see or hear anyone else. Beds were very comfortable. The entire apartment was spotless, and had only the basics without any junk. No rugs, so easy to clean. Great access to the Metro, and everything in Paris. We loved being able to pass by Hotel d'Ville, cross the Seine on our way to walking over to the Latin Quarter to see Notre Dame and restaurants in Saint -Germain. 5 min walk to Le Marais with amazing restaurants and patisseries. Walkable to everything, and the area felt very safe, even after dark. You could hear some low level street noise as the windows face a busy street, but if you turn on the portable fans in the bedrooms you cant hear it. We loved having 2 cozy bedrooms and a kitchen for the same price that we would have paid for a hotel.
