I stayed at Fari's place from about 3 weeks and it was just amazing. She is a gracious host and just so nice. The house was always clean and had all the amenities to make your stay comfortable.
Location: The location is amazing- around 8 mins to the circle/Hammersmith line and about 13-15 mins for the central line. Also very conveniently located to Europes biggest mall- Westfield.
Stores/Grocery: There are alot of general stores and grocery shops around - so you can buy your stuff to cook.
Dog: They have the cutest dog and she is very friendly.
Another great point is that there is a lift in the building, which is helpful if you have luggage.
