We have stayed in this flat the last two years - both in October. We came back for the view and location! The window overlooking the Seine brings Paris into your flat - we often left it open/cracked so we could hear the boats, horses, etc. through the night.
The bed is comfortable and we sleep well. The bathroom is uncomfortable as you can't fully sit straight on the toilet due to the placement of the bidet, but it is tolerable. The hose for the shower isn't quite long enough for someone to stand and use it if you are over 5'3". The furniture provided is all very interesting and antique, but essentially nonfunctional, aside from the bed and the couch. Again, all tolerable because of the location and view. All part of the compromises one makes during travel.
Charles is lovely to work with and always very accommodating when checking in and out.
