This is a fine hotel, in line with the reputation of the Park Hyatt brand, but it wasn't quite a five-star experience. The Club King room I was given was comfortable and efficient, with a large jetted tub and marble tile in the bathroom. Bed was sufficiently comfortable, if not otherworldly. Plenty of outlets in the room, but curiously, none of them in an easy place to use by the desk, especially with a large universal converter. All of that was good enough. The only real issue I had with the room itself was that the shower had mediocre water pressure.
The restaurant offers Hyatt Diamond members free continental breakfast in the hotel restaurant (or in the club lounge on Sundays), with the hot items available for an $8 supplement. The breakfast is otherwise $40 all-inclusive, and while that's a bit expensive, the spread was varied and well-put together. It was worth the expense. The club lounge was otherwise empty during my two-day stay.
I was a little disappointed with the spa, which looked gorgeous, but didn't have much to offer. Machines were unimpressive in the fitness center, and while the pool might look beautiful in brochures, it has three small lanes, no general area to wade around in for those who aren't swimming laps, and the temperature was uncomfortably cold for a winter's day, even indoors.
Finally, although it might seem that the hotel isn't in the thick of things on Google Maps, I was actually very pleased with its location in terms of exploring Melbourne. By virtue of being within a five-minute walk of Parliament Station, the hotel had quick access both to the Melbourne train system and the extensive Melbourne tram setup.
I'd absolutely stay here again, and much preferred it to the Grand Hyatt that's less than a mile away.
