Location and price were excellent. We paid about $200 a night (booked room 3 months before trip). Just across from the Luxembourg gardens; metro a few steps away. Step out of building and turn left, and a few blocks away you'll find all kinds of awesome restaurants. Step out and turn right, and within a few blocks, you'll find Luca's--another excellent restaurant!
The hotel, rooms and bathroom were exceptionally clean. The black out curtains were a boon at night.
Our only complaint was a slight sewage smell in the bathroom when we first arrived--noticeable but not overpowering, and again surprising because the bathroom was spotless. So maybe this has to do with sewage issues in general in Paris? In any case, the cleaners opened our window to air out the room the next day while we were out and about, and that seemed to dissipate most of the odor.
Taxis were plentiful, though this is a pretty walkable area. About a mile and a half or so to Louvre, etc. We had planned to walk everywhere, but due to a back injury, ended up using Uber or taxis.
We did not have the hotel breakfast; we just popped into various bakeries ("patisseries") and every single one was lovely.
I would book again here, the initial odd scent notwithstanding, because the hotel is super clean, the staff helpful, the location perfect, and the price point manageable on a modest travel budget.
