Valerie's place is in a historic building right on La Mouffe. You can walk downstairs to the market, with some of the best produce in Paris. Moreover, Valerie is responsive and friendly.
The only issue to bear in mind (not in Valerie's control) is the noise from La Mouffe. It's an active market and a social area on the weekends, which means that I put my earbuds to use.
But if you're a deep sleeper, can't beat this location.
