Nicole's place is great - really beautiful, sunny and fresh!
The apartment and accommodations are clean and comfortable, Nicole and her roommate Fanny are lovely hosts and the terrasse is simply amazing!!!
About the logistics, subway is about 3 blocks away and you can get mostly anywhere in Paris within 1 connection. Some small groceries and restaurants nearby too.
I'd certainly recommend Nicole's place and hope I can stay there again when back in Paris.
