Overall this is a very charming place with cute decoration and in an excellent location. The metro is only 2 blocks away, location is very central to anything you may want to do in Paris, and there are many great restaurants and shops nearby. Very romantic Parisian views when you open all the windows/doors.
That said, the place has false advertising on a few things: breakfast provided (false), luggage drop off available (false; there is a 3rd party service called nannybag which they use), shampoo/conditioner/body wash (only got 2 tiny pouches of combo shampoo/body wash for 2 persons for 3 days). Overall clean but some things not quite right (e.g. hand soap in bathroom was empty and there was tiny plant growing in kitchen sink).
Some FYI:
The check out is pretty early at 10:30AM.
The place for check in is ready for 4:00PM. We were told the key would not be available until 4:00pm and there was no flexibility on that. However, we were in the area and decided we would sit and wait for key to arrive. Turns out, it was already there an hour prior. Seems like there are many people managing this property and some lapses in communication among them.
This is a traditional apartment building with no elevator. I would not recommend staying here if you have any physical limitations as it is many flights up steep staircase with the luggage.
