We enjoyed our stay on the 45th floor. The apartment is compact but comfortable, with a memorable view from balcony and bedroom window. For those who are used to quiet nights in the suburbs, even though you're on the 45th floor you *will* hear the trains rumbling through the night! (We got used to this after the first night or two and slept well - the bed is very good.) Location is excellent - Spencer Street Station is literally across the street, there's a Coles supermarket and other shops within sight of the building, and there are multiple tram lines close by (including the free CBD circuit). We also appreciated the late check-out - thanks guys. (Final piece of advice - avoid the elevators at 'peak hour,' when all the other tenants are coming home. There'll be a queue!)
