The only minor quibbles would be that when the Metro is in operation, you can detect a very faint rumble as one passes underneath: not enough to disturb sleep however! Also, the wifi dropped out of service more than we could use it, so I hope that improves.
From the greeting at the door, to the friendly reception team (perfect English by the way!), the careful attention to detail (coffee machine, vanity kit, hair dryer, moisturiser, shampoo , conditioner, shoe shine kit, sewing kit, well-stocked mini-bar, safe etc), excellent cleanliness, great rooftop bar with splendid views.... The staff were knowledgable and helped plan routes / trips around the city, and guided us with regard to public transport. I would recommend this place and plan to revisit next year!
