PhD Candidate looking for room in SW / W London

Hello! I am a 25 year old funded PhD Candidate in cybersecurity at Royal Holloway looking for a room in SW London. I am looking to move in at the beginning of September, but am very flexible in terms of which exact day that would be. I am Canadian originally, but have lived in the UK for ~3 years now. In these 3 years I have both worked and done my masters. I would ideally like to live near a train station, with the ability to easily get to both central/south London, and also Egham. I don’t have any dealbreaker room requirements. I quite like it around Richmond, Twickenham, Putney, Battersea, Clapham, and so on. I am a clean person, and in my spare time I like to cook, get drinks, head to a forest, or go to a show. I also like to just chill on the couch and read (I would really prefer to live somewhere with a lounge). I like to socialise but also need that balance (like most of us really I suppose). I do not smoke and I have no pets. I am looking a space for minimum ~6 months, but I can really stay indefinitely. Budget ~850 per month. Thanks!!!
