Natasha's place is excellent for a business trip or any trip in London.
It was very easy to communicate with her, and the place is clean and just about 10-15 mins walk from the underground, or if you have heavy luggage there's a bus right by the station.
I had a single room with a twin bed, desk, and a closet. the bathroom is clean and she provided towels. I did't need more than that for my 4 1/2 days trip and it was really nice to come back every night to a very quiet place and safe neighborhood.
In addition, the place located between Heathrow to central city on the Piccadilly line, so if you arrive from Heathrow airport it's really convenient!
