I recommend anyone who wants to visit Paris on their own.
+An affordable hotel. Self-service breakfast - of course without bacon and eggs, but rolls, tea/coffee, cheese, jam. Without limitation.
+ a minute away is a convenient self-service store with a good assortment
+ the metro is 5 minutes away, the train station is 10.
+ universal location for self-guided sightseeing and shopping.
+ entrance to the hotel by internal combination lock at any time (without cards and concierge)
- I didn't find it in it (but I say again that the hotel is for "no show-offs")
