I had a flight from Heathrow so instead of staying in central London I decided to stay at Natasha's place since it's only a few stops from Heathrow on the tube. It's a 10 minute walk from the tube station.
The room was clean. Natasha was very friendly and offered some tea and snacks.
Natasha has several rooms. My room (#4) had a very good table and chair, allowing me to get some work done but I'm not sure if every room has a table. Internet was working well.
Pay attention when you use Google Maps: you will go right past Natasha's house. When you turn into the street, it's the 4th house on the right (the last one). If you reach a road, you've gone too far. OpenStreetMap has the correct details.
