Carolyne and Romeo were very friendly, helpful and welcoming. I reached the apartment at about 8 pm on a weekday and they took time to show me around the apartment block and where to walk to get food. They also let me collect my luggage at a time after checkout time so that I needn't lug them around.
The apartment's a very short walk away from Federation Sq/Flinders and there's a tram 1 stop right outside the block. Extremely convenient! The apartment itself was cosy and decorated with many inspirational quotes. Night view's awesome. The room was comfortable and clean, with a toilet that's right outside it. The estate is pretty quiet so you can expect a good rest each night. I didn't use their facilities but if you'd like, there's an indoor swimming pool, steam room and a gym.
Thanks R&C! :)
