The wife and I had a great stay a Sergio and Shins little studio apartment. The location is super convenient and the studio itself was gorgeous, clean and provided you with everything needed for a enjoyable stay in Melbourne, the stunning views from the 25th floor were quite enchanting too! Sergio and Shin were super responsive when contacted via email and because they weren't in the city when we arrived their friend Lina, who was also super friendly, showed us the apartment.
Definitely a great first airBnB experience, would greatly recommend!
