We are a family of 4 (with 2 kids 4 and 5). We stayed 4 nights in Melbourne and this flat was good for us. We used the sofa bed in the living room.
Our arrival and departure times did not enable us to meet Deana, but communication was so smooth, accurate and complete, that it was easy for us to get to the flat and settle in.
The location is great, as it is within walking distance of a lot of activities : the beach, artisan market, various stores, accland road, penguins, etc. To go to the city center, the tram is only across the road.
Also, note for future guests : from the airport a bus (skybus) can take you to St Kilda directly, but the service stops earlier than the one going in the city center.
Overall a big thanks to Deana and a great stay.
