Agnes' place is exactly as she describes. Agnes is a delightful, warm host. Her place is clean and cozy. Hundreds of neatly stacked books line the shelves that hug her spiral staircase--a bibliophile's dream.
The building she lives in is quite special, too. I was taken by it as I approached and was so pleased when I realized that was where I would be staying. It is The City of Eiders by architect Mario Heymann if you are curious.
She is very close to the 7 line of the Metro, so getting anywhere in Paris from hers is easy.
If it was available next time I was in Paris, I wouldn't hesitate to book it again.
