We really enjoyed the sights of Paris, the neighborhood, and the view. The Airbnb listing is deceptive. The picture shows the room (12 ft x 12 ft), not what I'd call an apartment, with the sofa bed folded up. This makes the room look a lot more spacious than it is. The listing says it has 1.5 baths with private WC on the landing, and a high quality comfortable sofa bed, dedicated workspace (I don't know where), and that it can accommodate a gathering of 25 people. None of these are true. It is a 0.5 bath in the room, with the WC (toilet) down the hall. The bed sags a lot in the middle and was not comfortable. He does say there's no elevator but doesn't say it's on the 5th floor with 100 steps.
We are older adults and I would not stay there again. This studio seems more appropriate for young people used to youth hostels and bare bones accomodations.
