Abi met me half way to the bus stop, since her place was a bit difficult to find at night when I arrived. She also helped me to carry my baggage upstairs because there is no elevator. Her place is simple, but it has everything you need. There is fruit, water, coffee, etc. so no need to immediately go out and shop for basics. The room is large and includes a large bed, and a office style desk and chair. Her location is good. It's near a subway station, and several bus stops. I recommend taking buses so you can see the city, unless you are in a hurry when subway is faster. If you have heavy bags, the bus is simpler because there is no need to go downstairs and upstairs like you would at a subway station.
Abi is a great host. She even helped me with my bags when leaving, all the way to the bus stop.
I would recommend her place to any solo traveler visiting London.
