The rooms actually look pretty good for their age so I wouldn't let it put you off staying here. I stay a couple of times a year and always enjoy the club rooms.
Decent size club lounge - breakfast and cocktails both have good food. Only downside is happy hour finishes quite early (8pm I think).
Rooms are a decent size and look like most Hyatt's and always clean.
Staff are friendly and helpful, one even went looking for a Taiwanese flag for me for a meeting I was going too.
