Great location, clean and new apartment, and friendly hosts! It was located in a convenient area of the Melbourne CBD and places such as Flinders St and Bourke St were not too far away. The rather large Coles supermarket was a 5 min walk away, so it was really convenient.
The only downside was that the actual address - 639 Lonsdale Street - is located along a bus lane, so we had issues with the Transdev Melbourne buses sounding their horns aggressively whenever we wanted to alight from or board our taxis/Uber cars/private tour minibuses. I would suggest alighting or boarding at 220 Spencer Street, and then walking in via the Upper West Side pathway.
Otherwise, it was a fantastic stay and I would certainly stay there again when I return to Melbourne! Highly recommended (:
