Level is the name of the executive lounge at Melia hotels, however, the concept is slightly different from other chains. Generally, the opening hours are more generous and increasingly, they are marketed as a separate hotel. You do get access for cocktails if you are MeliaRewards Platinum, which I am not. So usually I book The Level and pay for it, but find it worthwile. (Unfortuantely, due to the pandemic, most Level areas are closed right now).
