I highly recommend staying at Alexandra's home. Everything was perfect as described.
Now I see why all recommendations are positive about this Airbnb place! :D
I do recommend staying here and traveling to Central London via Picadilly, District, and Central lines which are within 10-15 walking distance from Alexandra's home. Nearby there is a great Coffee-Breakfast-Lunch place to go - 11coffee&co at North Ealing where every day I was going/taking breakfast and coffee. For lunch/dinner I can recommend the Italian restaurant Cassereccio with delicious pizza, pasta, and prosecco which is in Acton Town.
For sure it will be my place to stay if needed in the future! :-)
