I've worked in the area a short walk away from the Station, and loved it. Clients were the usual mix really, and lots of guys coming up to London for work, meetings, shopping, AGMs etc., and usually with a bit of time to kill before catching their train back to Sussex. Busy and anonymous area, with small hotels that mean nobody checks out who walks by. Not many families with small children, which is also a bonus. Belgravia/Sloane Square/Knightsbridge are close, so lots of upmarket punters. I'd go back there like a shot... Good luck, whatever you decide.
