Professional Male seeks a room to rent.

I am a young professional male, moving to London from Switzerland for my career.
I am a friendly and clean person, keen runner and cyclist, and changing my career to become a financial adviser.
Looking for a friendly flat-share, ideally looking for a long-term rental agreement but I understand how the market is in London.
It will be a quick turnaround, the move, as the position will be tarting from the middle to end of next month.
