Two students from Finland are looking for a room

I am 32 years old woman from Finland and I am coming to London 1st of january with my fellow female student. We both start our work placement at then. Our practice period will last 3 months (It will end 5. 4. 2015) and we are looking for a nice room for that period. We can rent two rooms max 600?/per month each from same flat or we can share one bigger room and pay a bit more (max 1200?/per month). We are very friendly and down to earth kind of persons. We respect other people and their privacy. We both study cultural management in Finnish University of Applied Sciences.
