Earth Science Postgrad for West/NW London share

I've just started my Masters by Research in Earth Science and I'm looking for a friendly, chill house, somewhere within an hours commute of Royal Holloway but still in London (inside the M25).

I'm a tidy housemate and very focused on my work, but it would be good to live with people who like to hang out and chat around the house, as I'm moving from Bristol and apart from my girlfriend who lives in South London I only know a few people here.

I play guitar as well, especially acoustic and folk music, and could do with a decent sized double room as I have some instruments and equipment. I would also be studying from home a few days a week due to my uni being out of London.

Open to suggestions as to where to live and who with so feel free to get in touch! :)
