This is a note to myself. I must remember that for a journey from Central London (in my case Piccadilly Circus) to Heathrow you should allow a good 45 minutes. Heathrow is in Zone 6 which means I need a extension to my travel pass for that (thank goodness for Oyster as the pre-pay option which means you don’t have to think about buying a ticket while you are rushing for a train). The Piccadilly Line was quite a pleasant journey.
Off to Rome again.
