Looking for Room - Summer Season - May to Sept

Hi, Im looking to rent a room from mid May to mid Sept.

I will be going to london for a summer season contract, with Gorilla Circus Flying Trapeze School, located in The Regents Park. So i will be working most of the time (6 days a week). I live a healthy life, no smoke, no alcohol, Im a circus performer and coach, I will be working as an instructor.

Im looking for a nice place to rest and recover my energy (eat, sleep, do laundry and rest) since my main focus is going to be on the work I will be doing.

This will be my first time in London, before I was doing the summer season in Montreal, Canada.

Hope to hear from you.
Thanks
