Josephine's place was exactly as described in the site - secure, comfy and well-kept. The internet is super fast and both of us were able to manage work seamlessly with our kid on Netflix. The house is well equipped for both long and short-termers and is very accessible if we want to get to central London or even for high-street shopping in Ealing Broadway. For people with kids, there is a play area right downstairs.
Josephine was very accommodating for our flexible check-in request and was always reachable. During our stay, the microwave broke down and it was promptly replaced the next day morning.
She definitely lives up to the 'Superhost' name.
