We had a great stay here, and Amin was an excellent host! The apartment is very spacious, a short walk from Earl's Court station, which has both District and Piccadilly lines, and there are grocery stores nearby :)
When at the station, take the Earl’s Court Road exit and turn left towards the hotel. Note: When you reach the big black reception door, check the sign below the door phone on the left for the digits to press to reach the reception and be let in.
The best supermarket is M&S Foodhall, which instead is located down the road to the right from the station, but you'll also pass a Co-op, which is fine, as well as one or two smaller stores on the way to the hotel.
