Everytime you come to Paris you ask yorself how tiny is the appartement going to be, and then it gets even smaller :)
The appartement was under the roof in a great neighborhood in the 5th arrondisement. It is small and it's not to recommend to people over 1,80m because except for the small hallway there's not really a lot of space where you can stand upright.
There's no door between the shower and the room and you have to climb through the shower to get to the toilet.
It was absolutely okay if you don't except a fancy appartement and you're travelling on a budget.
The view from the window and the nice and lively neighborhood make up for the small space :)
