Academic who wants to be near green spaces

I just finished my PhD (in Sociology) and I'm moving to London to use archives around the UK (though the British Library will be my main focus). Ideally, I'd like to be within walking distance of some relatively quiet green spaces—parks, trials, etc.—and biking distance from the British Library. I'm pretty easy to room with; I've lived with roommates all throughout my PhD in Chicago. I keep my few things tidy and I'm often reading or out of the house. I enjoy living with others, but I certainly know how to do my own thing and keep myself occupied.
