ACCOMODATION ADVICE NEEDED PLEASE

I would greatly appreciate anyone who reads this and is willing to help. Im looking for a studio in london, preferably as near to City st George's uni of london, or for commute time to be no longer than 40-45 mins. In price around 300-360 per week (£1000-1300 per month). If anyone is willing to send options or websites where I can look for any.

It would be really helpful
