Hello, I'm traveling to London with my sister in November. She can't walk miles and miles as I like to, so I think being convenient to tube stations with multiple lines would be ideal. I like areas that are safe, with mid-range restaurants and cafes. Not super high-end, but some fancy is fine. There should be restaurant options for night time without major walks. Hotel budget mid-range and lower.
I have been looking at a few areas and have (I think) narrowed it down. Kings Cross (St. Pancras), Russell Square, Notting Hill. But open to other areas, it is just super hard to narrow down. Not into theatre district area.
Thanks!
