We stayed at the South Yarra apartment and the location was fantastic - incredible views from the 30th floor. The apartment was clean, stylish and well fitted out and the beds very comfortable. Alex was helpful and friendly, and responded immediately if there were any minor problems (e.g the hairdryer not working - this was replaced within a few hours). The location is amazing - very close to trams and trains, but not at all noisy. We didn't get to use the spa, gym etc., but I'm sure they were great too. All in all, fantastic value for money and highly recommended for your Melbourne stay.
