Arleta's place is located at a great location. Even though is quite long distance from central London there are multiple alternatives to move around with public transport. Arleta lives there but keeps to herself mostly, she will help you with anything you need still.
Only downside of the flat I would say is the fact that the bathroom doesnt have any vent or window so it gets pretty steamy in there. Besides from that, the room is a bit small but should work for a short stay just fine and you get the appt for yourself most of the day in case you need a poace to work and enjoy to cook at home.
