Daniel and Katrina's place was perfect! Firstly, the location: it is right near Southern Cross Station, so when catching the bus from the airport, it's about a 5 minute walk, or a one stop tram ride (free!) to the apartment. It is also located right on several major tram lines, which take you straight into the heart of the city.
The apartment itself is small, but it has everything you'd need. I wouldn't recommend it for a family with kids, but for a single or couple, it's absolutely perfect. Everything was clean, the bed was comfy and there were plenty of little goodies, coffee, tea, snacks, etc!
As hosts, Katrina and Daniel were perfect, communication was almost instant, and they were super accommodating to any requests we had.
We would definitely stay here next time we're in Melbourne!
