If I could live anywhere in Paris, and money were no object, I would choose Montmartre, despite the tourist hordes. The endless steps and steep roads would keep me fit, and there are still many quiet picturesque corners if you know where to look. Plus oh, the historical artistic associations! Of course, in the 19th century Montmartre was anything but posh and expensive: it was a scrappy little suburb full of rebellious smallholders (marking the start of the revolutionary Paris Commune in 1871), poor working class people, bars and cabarets. Artists flocked there because it was cheap and provided an excellent spot for people-spotting.
