1 room flat of 50m² in London

I am looking for a short term tenant to rent my one bedroom while I am away. Its a very clean and quiet one bedroom flat in a modern build with furnitures. I am looking for someone who is able to stay for 3-4 weeks with flexible dates from end of June to mid July. Must be clean, responsible and pay upfront. It is in a very nice and safe area with lots of shops around and 10mins walk to the King’s Cross station. I am able to share pictures upon request.
