The house itself is recently refurbished and immaculate. I didn't see or need any staff.
Unfortunately it was really hot in London that night and the traffic noise outside was really loud, so we either had a choice of being too hot or it being too noisy. The room we stayed in was ground floor, front room and there is nothing between the windows & the public pavement (a few feet away) which also made opening the windows a concern. Would stay there again but in a different room.
