Katie's place is absolutely stunning, spacious, and a perfect place to stay in for families. It is in close proximity to public transport (~10 mins walk) and grocery stores, as well as being located just a hair away from central London which means you can enjoy both the city and the quiet at your preference during your stay.
Katie and her family gave me a warm welcome and tour to her place prior to our stay (I live in London), which was great because it made our communications easier after meeting face-to-face.
I definitely recommend this place to others who are looking for a place to enjoy their stay in London!
