We stayed at this former Hyatt Hotel May 21/22 2013, and while I have no complaints I do have a couple of observations.
The stay was part of a package tour (China Best Tours, out of Sydney), and it was listed as 4.5 stars. I'd only go 3.5 to 4, because of a couple of minor problems.
Free wifi was supposed be available in the lobby - and it was, sort of.
In the piano bar, the wifi was quite good - but in the lobby area itself, and in the second guest seating area it was inadequate or non-existent.
That meant we had to sit in the piano bar, near the wifi router - and gently shoo away the staff who assumed we wanted to buy drinks or coffee.
That brings me to a second quibble ... A group of about six of us DID buy some coffees and cocktails and beers while sitting there. The coffees were apparently undrinkable (not unusual for China), the Margaritas were acceptable, and the beers were Tsingtao, so how could that go wrong? :-)
But the complete lack of English meant that three of the six orders were either mixed up, or had to be changed because "no more".
And finally, while discussing the lobby, the toilets next to the piano bar had no paper (not unusual for a Chinese toilet) .. but they also needed cleaning, and two of the stalls in the mens room had broken locks.
On the other hand, the location was excellent, the rooms spacious enough (and with a cute 'rice-paper' screen to diffuse the lights from outside) and the breakfast was perfectly acceptable (if not exceptional).
I note that others has commented on the very hard beds .. again, this is not unusual in Asia, so we just accepted that.
So - overall - the Grand Metropark is a perfectly adequate hotel, but really only 3.5 to 4 stars, not five.
Having said that, we were on a package tour which had kept us on the go non-stop for days, so all we really needed was a bed and a shower - and it had both of them :-)
