Get a 2 bedroom apartment in the following areas, your own lease, and rent the other bedroom out. Then you have a little more control of how things turn out when living with other people..
Aberdeen
Ap Lei Chai
Chai Wan
Tin Hau
North Point
Kennedy Town
Wan Chai
Causeway Bay
Aberdeen Street ( near LKF ) and down the hill ( LoHo )
Happy Valley, lots of low rise walk-ups, higher floor=cheaper rent, and if you can get a roof top or terrace, BONUS !
Luck is going to play a big part in how this all pans out for you, having just a weeks company paid accommodation to find a new pad that's, semi nice, no easy feat at the best of times.
Good luck, being single and without family responsibilities, makes compromising on property a lot easier to tolerate. you will be fine.
