I felt extremely comfortable at Grace's place!.
Grace is a great hostess, always very friendly, helpful and in a good, positive mood.
The room was very big and clean. Good idea to take off one shoes before entering the house - thus the carpet remain clean and you feel comfortable.
Also the bathroom was very clean although several people used it.
Breakfast was perfect for me - the frige was filled with bread, jam, cheese etc.
You get to the next tube station Brent Cross or Golders Green in 10 - 15 minutes by walk. From there you can take tube or bus to get to Central London. The distance is not that far - at midnight you can take the night bus back to Golders Green and then just ten minutes walk back to Grace's home in a peaceful neighborhood. I also like the atmosphere of Golders Green with many different shops, cafes and many different people. Even at midnight I was not afraid to walk there on my own.

I can highly recommend to stay at Grace's home.
