Fabulous stuff - a joy to read from start to finish. Your evident delight in every detail shines right through. ^
I was glad to see that you meandered along the charming main street of the Ile St. Louis, which is my favourite Paris stroll (probably because it's the first thing we did on my first trip to Paris - on a gorgeous early summer day it took us most of the day to walk that small distance, including obligatory stops for coffee, drinks, shopping and a long lunch).
Already hoping for another
mwp2paris adventure - even if it's just a mundane trip, I'm sure you'll do what you can do with what you’ve got!
