Stayed for 12 nights. Sue was very accommodating and empathetic with our situation as we were stuck in Munich due to flight cancellations and arrived at the apartment a day later.
The apartment was gorgeous and was exactly as described. We felt at home right away.
My only regret is we didn't make use of the rooftop as it was cold and raining in London.
I will definitely recommend to stay here if you don't mind the 7 min walk to the Underground
