How did you manage this? Was this daily? If not, where were you sleeping when you were in London? Where were you flying to, and how were you getting into central London? I'm really interested in commuting to London from other countries but it seems impractical and expensive. There seem to be a lot of people talking about how in theory it's cheaper, but no one is doing it other than weekly commutes, which requires a place to stay in the first place.
