I've read the reviews and I've seen that everything I want to say is already written. I'll emphasize the top 3:
1. Patrick - he is a great host! Polite, caring and eager to help at all time.
2. Location - the apartment is the the double dd inside the word "middle". It's inside a beautiful and quite Parisian neighborhood. Close to any site worth being.
3. The apartment - very comfortable, designed beautifully and with great taste. Awesome shower!
I absolutely recommend Patricks apartment.
Travel safe.
