The good: the apartment is cute, affordable, and the location on Île Saint-Louis is *very* convenient. The space is small but cleverly designed (aside from a bean heading into the bed area which I managed to bump my head on ten times :) ). The bed itself was also quite comfy!
The space has good potential but needs some key improvements. The shower interior/exterior was quite mildewy and needed scrubbing. There are also signs of moisture/water damage on the kitchen's ceiling beams below (white fuzzy mold + some peeling paint). A drying rack or dish towel for dishes would be appreciated. And we were left with *one* single coffee pod + one small roll of toilet paper for a 3-day stay (it's possible I overlooked where provisions were kept but I looked everywhere). I certainly don't mind buying toilet paper but I'm not keen on hunting down Nespresso pods :).
Lastly, I understand the space is small but some more comfortable chairs or a place to sit would be great. The ones provided are not really comfortable or practical for resting after a long day of traipsing around Paris. With some attention, this little apartment could definitely be 5 stars, as the price was very good!
