Charley's apartment is perfectly situated to enjoy living like a local instead of a tourist. The neighborhood is filled with hidden architectural treasures and excellent food and coffee. One recommendation is to familiarize yourself with the quirks of the Northern Line. Angel is the local tube stop but it's not reachable from every single Northern Line stop. The line has two branches, but this is not indicated on the signs once you're inside the subway cars, and many Londoners don't know about it either. Delightful stay.
