The house is lovely in an incredible location (I would give the location itself 10/5 stars if I could!)
Harriet is lovely and super helpful anf the room itself is cosy and comfortable :)
As a solo female traveler I felt very safe both in the house itself and also in the neighbourhood (despite close proximity to high street and more busy areas, the street is really peacefull and quiet even when your getting home quite late).
I would definitely stay with Harriet (and Topper :) ) again next time I'm in London
