The location of this hotel is fantastic, and for the price it wasn't bad at all. We were on the 4th floor, and could see Notre Dame only a couple of blocks away out our window. Friendly check-in. Cleanliness was fine - clean bedding, clean towels. No service for our second night (no bed made, no clean towels), so make sure you hang your towels to dry. Bed was reasonably comfortable, and king size which is difficult to find in Paris.
Be aware there is no elevator, and the stairs are windy (70 steps to the 4th floor). A bit difficult to navigate carrying even small luggage, as well as after a couple bottles of wine. :)
