My husband and I stayed for the first 4 nights of our honeymoon and it was absolutely perfect. It was clean, charming, and in a super convenient location. Saul was easy to communicate with before hand and check in was great.
Two things to note:
1. It is up 5 flights of stairs so consider this if you are not able-bodied, pregnant, bad knees, etc.
2. It can get pretty noisy at night and early morning (normal city sounds). I would recommend bringing ear plugs if you are a light sleeper.
We would absolutely stay here again if we get the pleasure of returning to Paris!
