As earlier reviews suggest, wifi and plumbing could use improvement. The wifi extender upstairs did not properly work with my work MacBook so I had to make work calls from my personal hotspot on my phone in the living room, at my own expense, which the family also often wanted to use at the same time. One shower has no shower curtain, and the other has pipes that leak while showering, but the host still admonished me for flooding the bathroom while showering, which was also uncomfortable. Finally, the room is on the second floor and quite cozy so it can get rather hot at night. Finally, I felt several times like the family was not thrilled about my sharing their kitchen even though I'd paid to do so, and my belongings were moved around several times without prior notice.
In the scheme of things, these were minor issues. The neighborhood was not perfect but much better than I expected. The home and family were mostly lovely otherwise as well. The backyard is absolutely delightful.
If you need a quiet and clean place to stay in London for a few days and don't mind being far from the center, this is a decent option.
