Really enjoyed staying at Norma's place.
It was easy to get to from Heathrow with the Picadilly line - and to get back and forth with public transport in general.
The house is situated in a rather quiet road off the main road - next to a park which is great for running - if you have the urge to do so ;-)
The room was clean and had everything you ask for when staying with Airbnb and more - a very cosy bed, enough towels and fresh bedding/sheets after a couple of days (stayed >10 days) - and a separate bathroom.
Communication and check-in went perfectly fine - and there was always a good suggestion at hand when it came to e.g good places to eat around the corner etc.
All in all - a place to recommend! Enyoed the stay a lot.
