Stayed with Living Corporate in 2012 during a project in Melbourne (at the Downie Street building). The service from Martine and the team was fantastic (she even came one night to let me in after I locked myself out to save having to call a locksmith). The apartments are large (a lot bigger than a hotel room, but not five star, probably a solid four star standard). We negotiated a great price because we were staying for six months.
Pros – Great size apartment (we had a one bedder which was ideal for two of us), wireless internet and cable were a nice touch. The cleaners were really handy as well.
Cons – Only located in the Melbourne CBD, not in the suburbs. Sometimes need to book a bit in advance as they tend to be booked out a lot. Some unusual extras (like cots or airport transfers) they will arrange, but you need to pay for.More
