Authentic place in a fancy house. Really cool collection of fragrances inside. Liz was super nice and welcomed me even though my flight came pretty late - much appreciated!
The only thing please be aware the address is not exactly what Airbnb shows (their bug), type carefully from what Liz will send you, British addresses are a bit of a mess to my taste :)
It's just a 10 minutes walk from Paddington train station where the Heathrow express will take you.
