I loved my stay at Julia's place. It's super close to public transport and in walking distance to some really good restaurants and shopping. But I still felt like I was away from the hustle and bustle of London.
She's such a welcoming and kind person. She made sure I knew that she didn't expect me to stay locked up in my room. I had access to the kitchen, back yard (which is where I ate my breakfast each morning) common room area. Her cat is a fun little guy.
If you don't mind a small commute to get to central london, which is easy since the overground and multiple bus stops are super close, I highly recommend staying here.
