In the heatwave that wracked London while we were there, the Layfield house was a cool respite - I’m not exaggerating when I say the air conditioned living/sleeping spaces were a Godsend.
The house is a little older but had all the amenities we needed for our stay (and the house manual David & Shully included was very helpful). It was also a close driving distance to shopping (Brent Cross Centre), groceries (Waitrose at Brent Cross; Tesco not much further out) and to the center of London (about 20ish minutes).
The hosts responded quickly to questions; although in response to the questions, it was clear that one issue we saw/had was not going to be addressed before our check out.
Overall, a satisfactory London stay.
