I stayed at Karolina's place for about 3 weeks while she was overseas. Despite the distance, she arranged for everything I needed with the help of her local friends. When I mentioned I liked that she had a cat in her profile pic, she offered without obligation to let Louis (the cat) stay with me. :) This was a nice gesture, and I enjoyed his company. She provided for the cat's needs (food, litter), and she checked in on me a few times to make sure everything went well. She was also flexible in allowing me to extend my reservation twice. Her local friends were helpful and attentive if I needed anything (including someone to watch the cat for a night while I was away).

The place itself is comfortable, well kept, and in a secure building. It's close to some great restaurants on Victoria Street, and it was easy to get around the city from there. The downsides are that there is no microwave, there is only limited internet (via 3G), and the washer is currently not working (Oct 2015). Nevertheless, I would recommend it for anyone visiting Melbourne.

Note: I learned from experience that Louis likes to knock things off of shelves, so if he stays with you, be sure to put anything breakable out of reach.
