Check-in time may have been due to an event at the hotel. I arrived past 3pm but the room wasn't ready yet, they said it was still being cleaned and prepared. So I waited for about 30 minutes. However, when I got to the room, the cups and coffee area in the room were very dusty. Then, the sofa area in the room, even though it was a non-smoking room, smelled strongly of cigarette smoke, and the sofa in the room had many holes from cigarette splashes and lots of stains, so in a class like Accor Group, things like that are not well thought out. For breakfast, there wasn't much variety, and it was very standard for a 4-star hotel in the class of Accor Group. Hopefully it will be improved in the future. Thank you.
