Marcus' place is very accessible to everything in the Perth area. It's a short walk to the river, and an easy stroll to the Northbridge area, and only a block to the central retail area. It turns out that the apartment is one of nine in the building: it's deceptively bigger than we had thought from the street-front photos!
Marcus left detailed instructions for check-in, which made it quite simple to get in, and also sent a very helpful set of local tips in the days leading up to our stay, and enquired how we were settling in after our arrival. The parking is in an off-street garage in the building, and can easily take a large car.
The apartment was well setup, with a cafeteria for coffee, heaps of bowls and cooking implements, strong WiFi throughout the apartment and reasonable speed internet, and a small eclectic collection of books and DVDs if you somehow find yourself struggling for something to do. There was heaps of storage, and enough room to be very comfortable. The top floor is an attic room, which was a comfortable retreat.
If you want or need to stay close to the centre of Perth, this is a great individualistic place.
