Davy P... thanks a million for your beyond call of duty effort in transporting us to Shkoder and back... Bus number 1 was the place to be, and our bus-steward was second to none!
Heathrow Express to Paddington 15-20m
Bakerloo Line - Paddington to Baker Street <5m
Metropolitan Line - Baker Street to Wembley Park 15-20m
the rest is down to how quickly you walk
you can buy Heathrow Express tickets on-board or save a bit buying in advance.
