Challis Avenue is a great location in Sydney and from the outside this seems like a fashionable 5 star hotel. However, the first "queen size" room ($250 per night for room 105) was completely unacceptable! Small, on the ground floor next to the fire door that was permanently open, a window that opened on to a courtyard where people spent time late at night drinking, a tiny bathroom with an inability to open the shower door properly - this was one star accommodation! I was mover to a better room (412) after two nights but even so the bath room was small, there was little or no room service (cleaning, bed making etc) but the towels were changed after 48 hours.
This is an expensive second rate hotel. The girls on the desk were excellent and very helpful. A great area but there is much better value available in Sydney. I cannotrecommend this establishment unless you are going to spend all of your time out of the room and you don't mind a tiny bathroom! I give it two stars - one for the location and the outside architecture and one for the girls on the front desk!
