Jeremie is a wonderful, attentive host. Although he was not able to greet us, we had no problems with checking in. The location cannot be beaten - right in the centre of Paris, very well connected to the metro and right next to a high street with lots of cafes, bars, shops - everything you need. Don't let the number of steps put you off, it's not that bad! Jeremie was also very kind and was flexible with our check out time :-)
A few things needed fixing in the appartment - the bed, the toilet seat, the shower door. The lock is quite difficult to open but you get the hang of it. The apartment is smoking so you must not mind the smell of smoke.
