26yo professional with cat looking for double room

Hi! I'm Raz, I'm looking for a room in London from July. I'm a 26 year old professional (art and retail) looking for somewhere that has convenient travel links, especially if it's easy to get to the tube (District/Northern line preferably) + Southwestern Railway.
I can provide a guarantor and work reference if necessary.

What I'm looking for:

-A double room that's big enough for/has a good-sized desk
-Tube station within walking distance
-Friendly, non-judgemental roommates who are up for having dinner or a chat together occasionally! (but also value personal space and quiet time)
-Cat-friendly, LGBT-friendly home
-Clean place with functional amenities and good wifi
-No dogs, sorry :(

About me:

I'm a digital artist, currently also working in retail. I'm a bit quiet and introverted, but friendly! I love art, fashion, video games, reading, comedy, theatre/films/TV and cooking (especially Asian food). I have a really sweet, timid, well-behaved cat named Kiki, she's very cute and she sleeps a lot.
I'm very respectful of people's space and make an effort not to be noisy or make mess. I keep common areas clean and tidy (I don't leave dishes in the sink!), and hope flatmates will also be considerate in the same way, so the house is pleasant to live in for everyone :)
I don't smoke anymore, but I use a vape sometimes, I can happily restrict this to my room or an outdoor area if that's preferred.

I'm looking for a place that can be my home, not just a room to sleep in, and ideally want a lease of 6-12 months.

My budget is about £900.
My hard move-in date is 30th July, but I'd like to come earlier if possible.
I will probably WFH 3 days a week.
I can provide a guarantor if needed.

If there's anything else you want to know, please feel free to message me, I check here every day!
