Over priced, poorly constructed hotel close to Sydney Showgrounds. My room had three walls and a corridor between me and the lifts, yet vibration from every lift passing was obvious all night. Booked a king bed room. Upon arrival I was as given a twin room. When I complained, staff said they'd push the two single beds together for me. They reluctantly changed my room to a king although claimed that type of room was more expensive than the $370/night I had already paid.
