I've just recently checked into the GH Fukuoka and I wish I had the same impression as

Hotel is sold out and while my reservation was honored, I can't say I'm too excited about the property.
In the last couple of months, I've stayed at the GH Singapore, GH Tokyo and GH Manila and this property ranks well below the others.
The room (Queen) is pretty small and has a vague cigarette / musky smell. I guess that's why a purifier was put out into the room before I'd even checked in. Bonus for the fact that there's a warning about using more than one electrical item at a time lest it blow a circuit. I've asked twice about changing rooms and both times was given a polite but emphatic "no".
FWIW, I have Globalist status.
