I have the nicest commute at the moment. I work strange hours so I'm never travelling at peak times, which means the tubes are not too rammed; most of the time I can get a seat. I just have to travel six stops, and I can get from home to work in about half an hour.
The hospital is in the City - an area of London that I know very well because I worked there when I was an accountant for many years. I find myself taking out my phone and snapping pictures every day, because this part of London is just so photogenic.
