We stayed as a family of four (two teenage boys) and had plenty of space. The photos are a little dated so not quite as shiny and new as shown but still gives an accurate idea of space.
The trains were loud on arrival as quite close but adjusted really quickly and did not affect sleeping. It was a great location and walking distance to everything with loads of eating choices around.
Instructions were very clear and easy to follow. The only issue we had during our stay was with parking as the key fob kept refusing to open the boom gate for parking.
We would stay there again if staying in CBD.
