It is a great apartment close to the hip areas of Collingwood and Fitzroy with plenty of bars/restaurants/supermarkets/... around. City Center is also close by and can be reached by tram. You can easily sleep with 2 people, 4 is more cozy but still fine.
We did not meet Maria in person, but communication was easy. The apartment was clean and as expected, checkin and checkout also went smoothly.
We would always come back.
