I'm not sure why this place has such high reviews--it's OK at best and far from "luxurious" as advertised. The only thing great about it is the location. Otherwise, the photos are definitely outdated, the apartment is WAY more cramped then the listing would lead you to believe, the bathroom (while renovated) smells funny, and the sofa bed is extremely uncomfortable and squeaky. I agree most with this previous guest's review:
"Avoid if you can. There are better, cheaper places in Paris.
We spent one night in this apartment and it was not enjoyable. If we booked this place for a longer duration - I would be furious. It is not luxurious. It is not cozy. It is close to Gare Montparnasse.

The pictures are old and designed to be misleading. The couch-bed is old, worn out and squeaky. The white table in the main picture? There is no place to put it away when you have to unfold the couch.

The apartment wasn't dirty but it wasn't what I would call clean. It is worn out and it is obvious that many, many people stayed in it.

Overall I would be extremely disappointed if I booked this apartment expecting a "luxurious" stay. If you are in Paris for several days - look for a better place. If you just need a place to stay for one night - there area cheaper options. Would only recommend as a last resort."
