Kate and Sam's place is exactly as pictured. It is absolutely lovely, well provisioned and in a very nice neighborhood. A very easy walk to the tube station so it was easy to get anywhere I needed to go. I had a few challenges with ReadyGuest around check in, but once I was in the flat they were very responsive to any and all questions I had.
I was on my own so the flat was plenty spacious for me, but if you a bigger party or particularly tall you may find the space a bit tight. Also as previously mentioned, you do definitely hear the upstairs neighbors. That said, I would definitely recommend Kate and Sam's place. I had a wonderful stay there and would choose it again if I get the chance to return to London.
