"(1) Punctuation: The shuttles were on time, and the drivers were friendly and professional. (2) Hospitality: The receptionist was so kind as to offer me a late check-out, given my evening flight, and to arrange the shuttle to the airport at my convenience. The next morning, the restaurant server helped me maximize my Accor membership benefits while keeping my budget in check. (3) Modern & sophisticated room design: smart lighting and rational amenities, just enough for what I need, yet saving space and investment for the hotel.(4) World-class Breakfast with hundreds of food courses from east to west. It's a nice surprise for the Mercure hotel brand. (5) It was a minus point that the Mercure Haneda Airport hotel did not offer Accor loyalty points, but I am on with Expedia’s keycast benefits."
