Ocassional accomodation in London or around the city

Hello there, peeps. I'm seeking for a few landlords who have spaces or rooms available for temporary living owing to my workload. I am fairly adaptable in terms of my job and location. I'm looking for a clean yet laid-back flat or house share; I'm not looking for luxury; instead, a standard low-cost quality will serve because I won't be staying for more than a month at once. Are you able to help? I am therefore happy to pay your bills on a weekly basis. A win-win situation. Stable cooperation in this area would be tremendously advantageous. Than you very much!
