AC broken. Front desk hard to reach and when I finally got a hold of them they sent their 'engineer'. He assured me it was fixed and would cool down soon. 2 am and the AC is still not cooling properly and I have to wake up at 6! The only thing they keep offering me is to send their 'engineer' again or to switch to another room but I would have to pack all my things first (again, it's 2 am)! At $350/night all I want is to be able to get some sleep but they can't help.
Service is terrible
