I stayed at the building on Sydney Street. The mansion is lovely but if you are assigned one of the old servant's rooms you should expect cramped re-purposed space that is difficult to reach down a narrow hallway. Suite 5 was furnished with whatever was left over. It contained a 2-burner electric cooktop / sink / refrigerator unit, dishware, etc. so it would be possible to live in it without eating out constantly, if this is important to you.
On the plus side it is an easy downhill walk to the harbor. The check-in process worked fine. I only stayed for one night and I would not stay in this room again but I might consider another property by these owners.
