The apartment is brilliantly designed and has great access to transportation. There were tons and tons of books available in many languages, a record player (with great record taste!) and some fresh milk and apple juice in the fridge. Everyday we found something new and exciting hidden within the apartment!
Main negative is that the pillows were a bit uncomfortable, but American's in general are not used to Euro pillows...lots of pillow with very little stuffing. Bed was comfy!
I'd recommend a stay with Cecile if you're a fan of design and a more authentic Parisian neighborhood :)
(Restaurant next door is fantastic too!)
