This apartment is gorgeous and definitely the right fit for someone looking for a romantic showplace apartment for a trip to Paris. I visited in April and the sun streams in all afternoon through sunset via the three large terrace windows facing the canal.
I was traveling alone and only used one of the two bedrooms. The main bed was comfortable. The linens were clean. The window in the room has both sheer curtains and blackout drapes depending on your level of light sensitivity while sleeping. A note that the second bedroom window has opaque panes of glass, so one doesn't exactly have a "view" out to the courtyard from it unless you open it. (It was still rather chilly in April so it remained rather closed.)
The big thing here is the beautiful living room, which has three distinct areas: one for lounging on the couch or having conversations by the fireplace, another for dining at a four-to-six-person table, and a third "office" area with an impressive wooden desk, great if you bring your laptop and need to feel like some sort of famous French author. And all this looks out onto the canal and your personal terrace. I had a few family members over for wine and cheese prior to attending a performance at the Garnier Opera (highly recommend!) and they were duly impressed by the layout, styling and views.
As others have noted, it's up five rather steep flights of stairs. As a New Yorker, I'm familiar with this type of effort in a domestic setting but for the elderly or less able-bodied it may be a bit of a challenge.
The neighborhood is fabulous and conveniently located near the Republique metro stop, with access to a few different lines to get you around Paris.
Pierre was able to accommodate my early arrival request (11am), which I am grateful for.
I mentioned this to Pierre, but it seems a previous tenant or guest smoked cigarettes in the apartment, and there was an odor that lingered during my stay. I was able to get beyond it, but for those who have strong allergies this could be a bit of a problem (although honestly there is so much smoking in Paris you may want to avoid the city entirely if that's an issue!). The Wifi was a bit slow by our highly connected/download-a-Netflix-movie-in-2-seconds modern standard, but I'll chalk that up to "old world charm." :)
