Laura and her partner were professional hosts. They responded promptly to my questions - I really appreciated that. There were several great points about the apartment. The proximity to central London: it is convenient and guests have the option to use buses or tube. The provision of a hair dryer and clean towels were much appreciated.
However, there were some points that will make it hard for me to want to return or recommend the place:
1) The apartment was located in a building that was poorly maintained. The structure of the staircase was compromised and the common area was not clean (not really the fault of the host).
2) They listed that there is a washing machine, but there was none. However, I can see how this might only be an inconvenience to long-staying guests (like me).
3) The shower does not have good warm water pressure, which is especially challenging on colder days.

If you are planning to stay there for a couple of days, maybe a week, this place is sufficient.
