They proposed me to move to London. salary: 70,000 pounds / year + bonus, etc..I will move me with my girlfriend, who will study in London, and i have some questions:1 - I know that London is especially expensive, this salary allows a young couple to live comfortably?2 - What are the best zone: quality / price ratio to live?3 - Culturally, where i come from, the consultant is seen as a person who has to work from 09:00 am -> 11:00 pm and weekend if necessary ... is the same thing in London?Thank you very much for your help.
