Deana was a great host. She responded quickly and was very helpful. The house is exactly what you see from the pictures. It was especially convenient because I travel with my young kid and You feel like home staying here because the house is equipped with cooking stuffs, washing machine with detergent and all. Deana was so sweet to have prepared snacks before our arrival (bread with jam and butter, milk, potato chips, basket of fruits).
Tram (line 16 and 3a) is just across the road that takes you directly to Melbourne downtown. Make sure you have a myki card because tram from St kilda to town is not within the free tram zone. Restaurants and cafe are within walking distance. However, many shops nearer to the beach have closed down so do not bother to walk further to look for food. I got a parking ticket despite Deana provided me with a parking permit because the parking lots in front of the unit (Fitzroy street) are taxi zone from 12am - 8am. I suggest you park at the street behind the unit if it's overnight.
I took a cab to the airport on my last day and it cost me $50.
