I stayed here for work. I specifically asked for a quiet room and was given what they claimed to be one of their quietest rooms, on the 18th floor. It overlooked a 4 lane road. Windows were not double glazed, so it was far from quiet! When I asked to be moved, I was told the other side was also street facing, overlooking another 3 lane road. Not a place to come if you want to sleep - unless you are a heavy sleeper.
To make matters works, they decided to give me a wake up call that I did not request - at 3.40am!
My computer could not connect to their wifi network, so I couldn't do any work while here.
The room was tired and dated - and needed a big refurbish.
I won't stay here again. Mantra on Collins is a lot nicer, and much better value.
