I will spend 5 days with Hilton London Metropolita...

I will spend 5 days with Hilton London Metropolitan, but the first two days really made me very unhappy. First night, I was nearly frozen! During winter it is only 18 degree in the room. The other day I call the hotel to send a engineer to come and check, cannot believe I have to change the room! The Air Condition has big problem to make the room super humid! Until now I do feel very unhappy, I will see what will happen next.
