If you can get yourself to Kings Cross Station, then the directions Christina gives you will get you directly to her place, just as if she was walking with you. The house has everything you need - kitchen/dining area, private room with private bath, stocked with essentials you need like soap and toilet paper.
Christina was attentive to my questions, answering within the hour. A welcome book awaits you in the room with check-in and check-out info, along with suggestions for food and entertainment. It was perfect.
I plan on coming back to London in the near future, and I will definitely be asking to stay here again.
Thank you Christina, for making my accommodations in London exactly what I hoped for.
