When I choose Sarah's place, I knew why! I never choose a room just for sleeping, i need to sleep in a place where i can be at ease.
In Sarah's flat, you can be solo: your room, and use the kitchen.... and the buses at the bottom....
And Sarah is the prefect landlady. She will give you all the tips, and make your healthy breakfasts.... and give you also a care..... and be open to what you do on London, that she can experience also...
