Seeking room for summer/possibly longer

I'm doing a trial for a job in London this summer and if I like it I'll be moving to London permanently. Hence I am looking for a double ensuite room for atleast two months from June 27th till early Sept. Very likely to want to extend the lease but I am flexible about it.

I'm working in tech and my pay is structured with a fixed budget per month towards rent and bills.
I like keeping things tidy and clean, and while I do often work late I don't like being loud/noisy in my room as it is for my down time and relaxing. I'm a little particular about not sharing a bathroom.
I like playing tennis and hit the climbing gym fairly often. Would be stoked to do board game nights!
