Recently spent one night in the Astral Tower. Lovely room overlooking Pyrmont. Fabulous views and a very comfy stay. Everything is on site so you don't have to leave the building if you don't want.
The only hiccup I had was requesting a bucket of ice to be sent up and was charged $8 for the privelege! That's beyond cheeky!! (I thought it was a joke, but made to sign and pay - go figure!)
