I really enjoyed my stay here - yes, like the other reviewers have noted, it is a sofa bed and it takes up most of the room once it is folded out - but hopefully people know this when they are booking.
The location is fantastic, close to two metro stations and a brilliant supermarket (Carrefour Market Sèvres).
The shower is also a great pressure and temperature compared to other places I have stayed in Paris of this era.
