Doris' flat is all about the location. It is minutes away from Pigalle tube station and Abesses tube station -so easy to move around Paris. It is also minutes away from La rue Lepic with all the different independent food stores. There are small independent restaurants everywhere... the area has a great atmosphere.
The flat itself is simple, clean, with a neutral decor and perfect for 2. A little cramp for 4 (note:you have to go through the small bedroom with bunk beds to go to the very small but funcitonal bathroom).
I would definitley go back there.
