We stayed here for 8 nights and had a wonderful stay! As tourists in London with a toddler, what we loved most was the neighbourhood and location of the flat. It's walking distance to Hyde Park, Kensington High Street, museums, and lots of restaurants/bars/grocery but yet it's nice and quiet in the evenings. The Gloucester road tube station is so close by and got us to every single place we wanted to go very easily.
The flat itself is larger than we expected, and clean and well equipped for an enjoyable stay - Stephen even left bread, milk, eggs, fruit etc for us which is such a nice touch. We arranged for a crib through an external company and Stephen met them before we arrived l to let them in and set up the crib.
