Accor have allowed the brand to be "enhanced" like this for some time now. Its original positioning was a novel idea, now devalued. You are never sure if you are going to receive a "free" breakfast.
The brand has been allowed to become lost in the mirrioded offerings in the economy range. It has turned into a budget Mercure as there is no standard. There has been many examples of Mercures "downgrading" to an Ibis Styles.
