I stayed here with my daughter (17) for her spring break in March 2017. Everything about the listing is accurate and Susie was a wonderful host, and incredibly flexible in dealing with some last minute schedule changes on our arrival. The proximity to Knightsbridge was great, as is the walking distance from Paddington and the Heathrow trains. Cabs run down the street all the time, and the supermarket is a 10 minute walk.
Overall, I've found my new home in London!
