The apartment was very well situated, with multiple public transport stops and dining areas around and a very comfy bed. The best thing was Lethelion's friendliness and helpfulness though. They were very attentive throughout my stay and even made sure to stock the fridge with extra cold water as I arrived during a very hot period in Melbourne.
One thing I would mention though, is that if you're sensitive to light and enjoy sleeping in, perhaps consider bringing a sleeping mask as some light does get in through the blinds in the morning.
