A nice room in a lovely house in a lovely area! Great place to rest and get some work done during your time in London. There is a desk in the bedroom with plenty of natural light from the street as well as the living room backing on to a beautiful, green backyard. A great halfway point between London Heathrow and the main part of the city - 20-30 minutes travel either way. Very easy location for transport - bus stops right at the end of the street and a tube station a short walk away will get you all over London quickly. The local area, South Ealing, is a great little town with lots of greenery and open spaces and great food options nearby. A short walk or bus to bustling Ealing Broadway where you'll find a huge multitude of shops and public services.
Ewa, the host, is very kind, welcoming and hospitable and will always ensure you have what you need including breakfast each morning!
Overall, I can highly recommend Ewa and her home as an excellent, central location for a solo traveller visiting London, especially if you are coming from LHR and want a peaceful and accessible location to stay outside of the city.
