I stayed at Serrin's place for five weeks while working at Uni Melbourne. With me was a colleague, with whom I shared the flat.
Check-in, the stay itself, as well as checkout was made really easy by Serrin, and the communication was always friendly, prompt and helpful. I do not know what more to expect from a host.
The apartment itself has enough space for two colleagues, is well equipped with what you need (including a nice coffee machine), and the balcony is really nicely and spacious. WiFi is great and offers enough bandwidth for your favourite streaming service.
We used Melbourne Bike Share to get around in the city and to work, which has a station about 10 minutes by foot nearby. For 10$ per month you can have as many 45 minutes rides as you like, a very convenient way to get around. For those who don't like that: The tram stop is just across the street.
We went jogging in the morning, and getting down to the Yarra River (and the Melbourne Cricket Ground) takes around 10 minutes, which was also really nice.
Victoria Parade around the corner offers great food and supermarkets, so getting your stuff for the fridge is also easy.
Small hint: As the apartment is close to the tram stop, consider some ear plugs for the night.
All in all I recommend Serrin as host and the apartment for a stay, no matter if for a short-term stay or a bit longer!
