This flat is not 5 stars but almost there, it is a great place to stay and I highly recommend it!
It is in a great location in a very quiet area just minutes walking to Trocadero and the Eiffel Tower. There are bakeries and small markets very close by as well
The flat is very clean and comfortable (we were 4 and it worked)
Things to know:
Trash is on the bottom floor next to the elevator (service door) thru a dark passage to the outside in the rear of the building.
I washed twice, which was great but I had no idea how to use the appliances and each wash took over 3.5 hours.
There is a table in the bedroom to the left as you walk in that has a drawer that you can't see and unfortunately, we found a drawer right before we left that has manuals to the appliances.
Be ready to buy toilet paper (they provided us with 2 rolls for 4 people staying 6 nights) trash bags (they provide one in the trash can) paper towels (they provide one small roll) and dish liquid (the bottle was practically empty)
All in all, I do recommend this place but it does require some effort.
