The bedroom (with en suite bathroom) is exactly what you need spending a couple of days in Melbourne and the view is indeed absolutely stunning! I spent half my time in the room looking out the window....
Adam and Crystal are the best hosts I've ever had with an AirBnB and are very uncomplicated. They will try everything to make your stay your best one ever.
My Tip: Also Check out the Pool ;)

Locationwise it is only a 10 min walk to Flinders Station and many good bar locations along the river. Same distance to Southern Cross station.
