Flat searching in London!

I'm looking for a flat or a room in a flat for myself and my lovely three year old dog, named Scout. She is well trained, very sweet, and loves to go to the park and go on hikes (and will join you on a run if you let her).

I am clean, easy to get along with, and respectful.

I am active and love to be outside. I do pilates, lift, and run almost daily. I also love exploring the city and trying new restaurants. I am social and like to go out occasionally on weekends, however I also love spending time at home.

I am ideally looking for a flat in a dog-friendly area and with some sort of garden or patio.

I am not fussy about the location, as long as it is near public transport.
