My sister and I stayed 4 nights at this place and had good time. Though we had a difficulty of contacting her that we arrived earlier than scheduled , she showed us around the house and brought an extra heater.
The flat was kind like a hostel if all the rooms were occupied but you can meet with people.
The beds were comfortable. The location was tube zone 3 but convenient for South, East sides. Mind Abby Road near this place is not the Beatles ' one .
