Professional woman looking for a room (w/ dog)

Hi all! I’m looking for a nice place to move into with my little Dachshund, so pets considered and people that like animals are a must (she’s cute). Ideally I’d like to stay in the west, north west, or north of London, but Southwest would also be fun. It would be great to have a garden or terrace area - I can just about keep my houseplants alive though so don’t expect anything other than lawnmowing… hoping for 1-2 flatmates to join me in a bright, comfy space. I work in marketing and advertising and WFH quite often, so it would be great if you’re okay with this. I’m clean, tidy, and I love to cook so would be nice to have the odd flat night-in.
