I stayed 3 or 4 times a year until I couldn't bear the rooms any longer. The standard rooms are TERRIBLE, for a hilton, most of the couches were so filthy I wouldn't sit on them. Bathrooms very 70's.
I recently reached Gold and the last time I stayed there I got an exec room (after pointing out to the desk guy that I was gold not blue as their computer apparently stated) - no complimentary wine or water or chocolates despite raising the concern with manager. BUT the rooms are 1000% on the standard rooms.
I'm there next week and hoping things are better in terms of recognition but will wait and see.
Location is good and I would echo the post about clarifying to taxi driver which Hilton you are talking about - I've been driven to the wrong one before but not really a worry as they are only 5 minutes drive apart and you certainly won't get out of the cab at the less salubrious one (you'll realise it's a mistake straight away, if for no other reason than the missing 16 floors!)
