Pros: The location of this place cannot be beat! It's amazing. Walkable to the Louvre, Latin Quarter, etc. Endless shops and restaurants right at your door. It also feels very safe and is surprisingly insulated from street noise. Loved that you only had to climb one flight of stairs too!
Cons: We had a horrible experience when we arrived. Ariel told us we could drop off our bags when we arrived around 1:45pm (check in is at 3). But when we got there, the previous guests were still there and the cleaning person hadn't come. We felt unsafe leaving our bags but didn't have another option. I don't know if check out times aren't enforced or what but it was not a good experience. When we returned at check in, the room still hadn't been cleaned! The cleaning lady ended up coming eventually and Ariel said he's going to refund us the cleaning fee, but it was a very unpleasant experience especially after so much travel. There were some other things like the smell of tofu being super strong in the fridge, loud neighbors, broken outlets, no single-serve toiletries, broken shower head, etc. that made our stay less than comfortable.
Summary: This place is "cheap" by Paris standards but I'd spend my money at a hotel next time! This was the most expensive place we stayed during our 2-week Europe trip.
