The staff were pleasant and helpful. The light switches were as confusing as hell, especially the icon for cleaning my room, which I should have been informed of when I first arrived. As as result, my room wasn't cleaned after my first night's stay.
For a 5-star hotel, I'd have expected alcohol to be available. Instead it was water or soft drinks only. There was a fridge in my room but there was nothing in it - no snacks or refreshments.
I found my room to be a bit scruffy in places (scratches in doors, a handle hanging off the wardrobe door, a switch hanging off a wall), which surprised me as the hotel hasn't been open very long.
Overall, I wasn't impressed with the hotel and have stayed in far better 4-star hotels and was disappointed with it.
