We had a pleasant stay in general. However, room ceaning service needs to be improved. Our group of people have a few bad experiences.
1) after returning to room after the day, there was a used mask left in the bathroom. There’s also a day without providing onsen towels and we had to bring over the mid size ones
2) the door of my friend’s room remained open after the cleaning service (a 3M sticker with なすし2 sticked on wall). Glad there’s no missing items
3) another room, there was blood and urine stint left on the toilet cover!
I hope the hotel can take it seriously as it indeed ruins the brand of IHG and bad customer experience.
