Expensive and crowded. Low quality of services. Customer service is a joke. Great internet connectivity. Mediocre food, unless you like Indian, which is everywhere. Crappy weather. Not safe at night (depends on the area of course). I lived in Docklands, didn't feel safe outside of my apartment. Difficult to get anything done without proof of address, so make sure to get a place as soon as possible. Opening a business account in a "traditional" bank can take weeks. Banking is very backward - unless you enjoy browsing PDF statements... I honestly don't understand why London is so popular. I was deeply disappointed and left after a few months. The only real upside is the job market, but as a nomad, you can provide services to London-based businesses from somewhere else.
