I had a great time in London and Alexandras place is ideal for exploring the city. There are very good connections with bus and tube, so it´s quite easy to get to Westminster, Picadilly, Notting Hill, etc...
The room is very nice and clean and it was very comfortable to have an en suite bathroom. Also Acton is nice and quiet and there is a small park near the house, which is good after a buisy day in the crowded streets of inner London. A 24h supermarket is across the street.
I can definitely recommend Alexandras place!
