It was perfect. The space is small but has everything you need. Drawers, place to hang clothes, good shower, small fridge. Whole place is in courtyard behind large, secure gate. Perfect for one person - or even 2 if one is willing to climb the ladder into the loft (I was not).
I am not one who needs much host contact and Dd gave me my space. The one problem that arose (wifi went out one day) I emailed him (from The Long Hop, bar down the street which has free wifi) and Dd responded and solved the problem within 20 minutes.
And the neighborhood is a dream. Mix of tourist friendly and regular French citizens going about their daily lives.
Totally convenient to Notre Dame, and a mile walk down the Seine to the Louvre and Musee d' Orsay.
