Our little family of 4 stayed here for 3 nights, and found it perfect for us. It's right around the corner from the Louvre and Chatalet Les Halles, and there is a supermarket just a minute away.
The apartment was clean and had everything we could have needed. Though the kitchen is small it's very well equipped, and on arrival there were snacks, condiments and milk in the fridge.
It is located above a restaurant so it's not the most quiet apartment but it is the pay-off of being so centrally located. The building required key tag access so we felt very safe.
The bedrooms were smaller than they seemed in the photos and there's not a lot of extra space but it was fine for 2 adults and 2 kids. Thanks Alain, we would definitely stay here again.
