Stayed here for 2 weekends on either side of a work trip. Location is very central without being in the city. Place is as described/ the photos show - quiet, sunny and nicely decorated. If you roll up the lounge blind you get a view over roof tops to a church from the couch. Well equipped kitchen if you're cooking. Plenty of trendy restaurants and bars a 5- 10 min walk away.
I found the bed quite hard, but this is a personal preference. However I did appreciate the electric blanket on cold august nights. You do need to lift your bags up a flight of concrete stairs (unit/apartment is in a block and you're one flight up from ground), so keep this in mind if your suitcase is heavy. Also the key box if you arrive tired and in the dark, is by the unit door and not at the front of the block.
Overall a good place to base yourself in Melbourne and should suit most people. Solo female travellers should feel safe here too.
