The hotel is a tall, skinny building with winding, narrow stairs to the rooms and no elevator. So keep that in mind. For Paris, it was an okay place to sleep for the night. It was clean and the bed was comfortable. It was secure, with a receptionist in view of the front door at all times. Good wifi in the room, but I was on the first floor so not sure what it was like higher up. At first, I had booked a single room but when I got there and he told me the singles were on the 6th floor, I asked to change to a double and got one on the first floor so just one set of stairs. There was a room adjoining mine and the walls were paper-thin but that's Paris. The room is small and the bathroom is smaller. I've seen bigger bathrooms on trains. Nevertheless, it did the job and it was clean. I pity very large people trying to manuevre in the bathroom and the shower though. And I could imagine that two adults in the room would be very cramped with your luggage and bags there too, although the bed is large enough.
I found the area was a good location and there was a Metro stop not far away. Getting to Notre Dame from there was just 5 or 6 stops. Cafe right outside the hotel. I didn't see any other tourists around but this was April so before the big tourist season.
