Pros
Place is sparkling clean, furnishing is modern, rooms are spacious and well lit. There a lot of restaurants/cafes/shops nearby. The place is close to Les Halles (15 min walk).
Cons
Neighborhood is kinda scary, full of trashy people and a bunch of old hookers hang around the street. Furnishing feels cheap (IKEA), it looks like it was renovated for renting, so no typical Parisian charm. The building entrance is very narrow, stairway looks dangerous and the elevator (also very narrow) didn't work in all directions.
Conclusion
Overall the place is great on the inside, but you have to put up with a lot until you get there. The price is a bit high for the neighborhood it's in.
