Single Room Wanted for 1 Male

Looking for a place to stay in London. Recently graduated from the University of Glasgow and looking for a job while staying in London. I plan on getting a temporary job until I can land a permanent job in my field.
I like to hang out but I do like some personal space as well. Would love it if the housemates aren't just housemates but can become friends as well.
The room must be a single room as I don't prefer sharing a room with anyone else. I don't mind sharing bathrooms but an en-suite would be amazing (though I am aware it's not practical to expect that for my budget). Would prefer if the rent isn't more than £600 a month. Other than that I just want to be around nice people :)
