The AC Lounge is the focal point of the hotel. A place where guests can relax in a comfortable, modern space while enjoying thoughtful design, perfectly made cocktails, wines, and a curated menu of small bites. During the day, the AC Hotels Lounge serves as a collaborative space where guests and locals can continue their workdays uninterrupted with all the amenities they need.
