This apartment was perfect for me as a solo traveler for a week. It is very conveniently located -- a short walk from La Republique metro with easy connections throughout the city, a good grocery store (Monoprix) about a block away, and a nice bakery just a few houses down. Also a pleasant walk to the Marais, Pompidou Center, Picasso Museum, etc.
The apartment itself is basic (to be expected for the price) but comfortable. The bedroom is on the ground floor, and the rest of the living space, including the bathroom, is one floor up with a pretty narrow staircase. The sitting area in the living room is pretty tight for two people. It was comfortable for me, and there is also sitting room at the table, so it's not bad. I should also note that this is Paris, so small spaces are to be expected. The apartment is very nicely located on the courtyard, so there is no street noise. The kitchen is clean and fine with a refrigerator, cooktop and microwave -- no oven or toaster.
