I did overnight at the Anara 2 weeks ago. Taking a domestic Garuda flight (CGK-MDC) in the morning was a piece of cake, only 5 minutes walk turning left of the hotel entrance without any terminal change.
My opinion is that the rooms are more comfortable than the old Airport hotel, even though they show some "indonesian" wearyness (ie design faults, like shower doors unable to prevent spilling water on the bathroom floor) after not even 2 years operation.
Problem with their breakfast is that it's open all night, hence everything is cold. If room temperature scrambled eggs and cold chicken sausages are not your thing better rely on toasts and mediocre coffee, even the muffins are dry.
