Two of us stayed at this apartment for six days. As others have said, it is close to the metro and very convenient for seeing Paris. The photos provided are honest but show the place a bit nicer than the condition we found it in. The small entry court yard could be delightful, but during our stay it had a ladder and storage bins in it, and the plantings (other than the ivy on the wall) were mostly dead or not tended. We really could not sit out there. A large bin full of used paint cans was in the inside dining area next to the entry door. I am guessing the owner is a painter and may think this bin is a sculptural piece. We considered it as an extension of the clutter that was in the entry court.
We never met the owner, Frederic, but he did help me, via several emails, to finally get the WiFi to work properly on my mobile phone. His assistant, Nina,who manages the place, together with her boyfriend, came over and tried for several hours to get the WiFi working but could not. Nina was generally helpful and considerate. I had never used an induction cook top, and had a bit of difficulty learning the ropes of this but after some instructions by Nina, all went well. The kitchen is furnished with only minimal pots and pans, and few pot covers; don't expect to do too much complicated cooking here, it's just not like home. It's ok for making simple breakfasts or lunches.
One thing that was a bit awkward for us was having the only toilet on the upper level, and both of us sleeping in the bedroom areas in the lower level. To hit the head in the middle of the night meant maneuvering up the spiral stairs and going through the living room to the toilet room.
In summary, I expected more based on the beautiful photos, but I was sufficiently happy with the place to be able to recommend it to others. I think this is priced correctly for what you get.
