I went on a trip to London with my two daughters 12 and 14 years old. The apartment is above a restaurant and on a slightly busy street. Despite of this the apartment was quiet and we were unable to hear any noise from the street even when we left the windows open (there was a heat wave when we visited). There's a Sainsbury's grocery story 1/2 block from the apartment and the Victoria Coach Station is 4 blocks away for easy access to the underground. The best part is there's a bus stop in front of the Sainsbury's grocery store just 1/2 black away from the apartment. You can catch the 24 bus which runs by the; Westminster Abbey, Houses of Parliament, Big Ben, National Gallery, British Museum and Leicester Square. We would even ride it to visit Piccadilly Circus and Covent Garden and catch the bus back to the apartment at night. The bus would drop us off at the same bus stop 1/2 block from the apartment.
We also tried a few of the convent restaurants that were located around the apartment.
