Romain's apartment is perfect for a single person or a couple traveling to Paris, and provides a more authentic location and experience than many of the hotels can. It is centrally located just a 10-minute walk from the Louvre and the Seine, but is far enough away to have a local vibe without all the tourist traps of being right on top of a big landmark. We tried several of the neighborhood eateries and bars and found them all fantastic. There are public transit stops within a few blocks of the apartment as well. It was clean and well-appointed - exactly like the photos. Romain has very nice decorative style.
A couple of things to be aware of if you have not experienced Paris apartments before:
1. There are about six flights of spiral stairs to get up to the apartment, and no elevator in the building. For us, this was no problem, and we even enjoyed the extra workout, but just something to note if you've got lots of heavy luggage. Being on the top floor offers a great view of Paris rooftops, though!
2. Since this is Romain's actual apartment, there isn't really any space to store or hang your clothes, since storage space is used for his things. Not an issue for us at all, since we were dressing casually and were only there a few days, but just something to plan for if need be.
Overall, this was an excellent stay, and having spent six month living in an apartment in Paris during university, I can say this one is extremely nice, functional, central, and comfortable
