1 room flat of 48m² in London

I'm Kota, a Japanese postgraduate student studying at University College London (UCL). I have been living in this flat since last August, but I am considering moving out now that the university semester is coming to an end. My flatmate is also thinking of moving out due to her job location, so this two-bedroom flat will become available. The flat is on the top floor of a block of flats on Holloway Road (Band C). I am looking for someone to rent the entire flat, but However please
