That's REAL charm of historical Paris! This apartment is in the house of 16th century... In the next house Picasso lived 20 years... In the house on the opposite side of the street Louis XIII was intronized... Apartment is situated half way between Notre Damme and Louvre (of cource on the other side of river Seine).
All the shops (Carrefour, Monoprix, Bio c' bon) and a lot of restorants, brasseries and bistrots are maximum at 5 minutes walk.
It's easy to find this apartment at first time (walking along the river), and its possible to avoid the crouds of tourists, walking on the other side of this street.
Apartment is much more better in reality than on pictures. It is ideal for 2 persons (bedroom with big bed and the room with camine on 2 persons), but we were 4 (family with big children) and everything was OK.
The only thing to be taken into account - spiral staircase is quite steep. But for us that was good training before climbing to Notre Damme!
As for me, it's hard to find better located apartment in center of Paris for such amount of money!
