Jennyfer is a very nice host, even thought I haven't met her, but that wasn't a problem at all. Check-in and check-out went just perfectly, with her very precise and simple instructions, as communication with her was always fast and succesfull.
The appartement was exactely the way she describes it, even better actually, because only once you're there you realize how great the location you're going to spend your next days is. And rue Sedaine is a really fancy street, there's even the "café des chat", where you can sit and drink in company of super cute cats.
If you want to spend a few days like a real Parisian, this is absolutely the way to go!
