The rooftop spa is beautiful, but didn't use due to high winds. Still had an inside spa/sauna that were lovely and clean on the ground floor. The rooftop is great for evening/morning views. Had a clean bbq area with inside and outside lounge area to enjoy your meal or to just relax and enjoy the views in.
With just a few tram rides and short walks we were all over the city checking out some awesome rooftop bars and other restaurants and historic sites. I was lucky to have someone with me who has a Myki card to use the public tram outside of the free zone. Beware of this when using the tram, as it did not look like "pay as you go" was an option without that card.
Cheers!
