(I would normally get the train...) but I'm visiting friends who have just moved to Hammersmith (near the Charing Cross Hospital) for the weekend.
It seems that unlike Putney, they can't get a visitor car parking permit for my little car. I'd still have to pay at the parking meter @ £1.10 per 30 mins, 8 hrs for all of Thursday & Friday.
Would anyone know of a better place to stash the car for a couple of days in the vicinity?
