This is a great place to stay if you have a layover or early morning flight. You need to take the U3 bus from the central bus terminal at Heathrow. Likewise, you can take this bus to the airport. It took about twenty minutes. Her place is right next to the bus stop so you don't have to go too far.
The room was clean and comfortable. It was probably the best place I stayed during my trip to the UK. The bathroom is shared with the residents, but it is clean and contains all the necessary amenities.
