We stayed at Rebecca's place during Australian Open this year and had a great time here :)
The apartment is in a lovely and quiet neighbourhood 1 block away from the tram so really convenient if you want to get around the city (pro tip: walk 1 station down south to get into the free tram zone). Walking distance to some great cafes and restaurants.
As most old apartments in Melbourne, this place doesn't have air conditioner so it can get hot in the summer when it's over 32C outside (it feels ok in the house when the outside temperature is below 32). Rebecca was really considerate and messaged us the day before the heat wave came to send some helpful tips to cope with that, and the two electric fans in the house helped a lot.
I'd highly recommend Rebecca as a host to anyone traveling to Melbourne.
