It would be very difficult to find a spacious and clean accommodation at this price in the center of the city at this price. Neried was a very kind host. She helped me with my luggage, washed the roof of the room where I was staying (to dissipate the heat) and also offered me her BBQ specialities that she had made for her friends.
The location is some 8 to 9 minutes walk, either side, to underground stations. There is a bus stop just in front of the location.
Would definitely recommend Neried's place to anyone visiting London.
