The room i was staying for 13 days is a single-bed room which's a bit small for me, yet Philo let me use the desk in the big kitchen when i need to use my laptop and I am thankful to her.
Philo doesn't live in the house, but is easily reached by phone / whatapp. Her response' s very quick.
The house has single-bed and double-bed rooms. Perhaps next time i travel to London again, i would book a doubled-bed room as the house is conveniently located.
