Quite impressed with the decor of the hotel. However, overall service levels were not up to the mark. Response times for room service orders (breakfast tea only!) was slower than I experience in other hotels during my business trips across Asia and beyond. On the first day, when I returned back from work, I found that, while the room was cleaned, the tray for morning tea was not yet cleared. More critically, I am yet to receive the invoice for my stay despite being told that it will be emailed. While I have received this survey email, I am yet to receive an invoice and planning to call the hotel Monday morning, since I need the invoice for my expense claim.
