Structure the week around neighborhoods
Instead of crossing the city constantly, give each day a dominant neighborhood or bank of the river. This makes the week feel more immersive and less like transport management.
The Marais, Saint-Germain, Canal Saint-Martin, and Montmartre can each hold a full day when you allow cafés and side streets to matter.
Choose smaller cultural moments too
One major museum may be enough in a single day. Paris often becomes more memorable in the hours around the museum than inside it.
A bakery breakfast, a market visit, and a canal walk can bring more balance than stacking attraction after attraction.
One reservation that is worth it
Book one dinner you will still remember six months later. It gives the week a clear anchor and lets the rest of your meals stay casual and flexible.
For the other nights, keep a short list by neighborhood instead of locking every evening. Paris rewards being able to stay near the canal after a good walk or linger on the Left Bank when the light is right.
