I have been living in London for over 2 years as a student. It's ridiculously expensive. However, there are options. What I like about the city is you can find many events anytime you want. It's active all year 24/7. There are so many foreigners and tourists which make the living more vibrant and less racist. London has sub-communities which I think is a good thing. Those communities bring their cultures, ethics and foods. Public transportation and restaurants are great. I used to spend 3-4 hours in Costa or Nero cafe without interruptions. Though if it's raining or summer season it could be hard to stay long. On the negative side, the UK suffers from slow and old bureaucracies making life difficult sometimes. It's not easy to open a bank account or to rent. The government systems are slow. Also, you will feel depressed in winter when the sunset is before 4pm and the temperature is 0c. All in all, everything is great about the city except the affordability and the winter.
