As long as you're looking for the basics in an apartment and intend on spending most of your time outside in Paris (as you should!), Romain's place is perfect due to short walking distance to l'arc de triomphe and the start of the champs elysees. The apartment is probably best for a single person to be staying there due to size of the apartment and lack of things to do within the apartment since there's no tv or speakers, little area for preparing or eating food, and a small balcony which is difficult to go out on or actually sit at. Romain was very responsive and helped me figure out the washing machine and how to air dry, as well as accommodated me with my uncertain check in time, and I had a good time in Paris while I was visiting!
