We have one afternoon in Paris. I want to get to Notre Dame, but anything else quick that we could squeeze in? Staying at Paris Renaissance Nobel.
If that is the hotel near Palais de Chaillot and Eiffel Tower, you could do worse than wander the gardens, look at the fountains and have a leisurely glass of wine.
Failing that, walk across from Notre Dame to the Left Bank, take in Shakespeare's ancient bookshop and have a leisurely glass of wine!
The booksellers stalls along the Seine on the left bank are nice to explore as you look for a nice place to sit and enjoy an aperitif. Tres parisiennes!
Do you have both the afternoon & evening? An evening cruise on the Seine with major sites lit up is really thrilling.
I wouldn't squeeze anything. I would walk there and back. That'll take up the whole time. If that doesn't appeal, try Bustronome for lunch. 90-minute trip departs at 12:15. The food is surprisingly nice.
