We had a great stay at the Nest! As others have said, the 4th floor walk up helps you burn off all of the calories you've eaten in French pastries. The location is really convenient, near the Chalet Les Halles metro station. There's also a ton of restaurants and cafes nearby (try the crepe stand just through the passage moliere) as well as a small grocery store around the corner. The place is cozy, exactly as the pictures show.
