Excelent localization in zone 1 with an affordable price. You can get the 24 bus (24 hour bus) beside Alessandro's studio or get the tube at Pimlico or Victoria station. It will take you up to 10 minutes by walking. Both of them will take you easily to the main sightseeings of London (Big Ben, National Gallery and so on). Alessandro and his staff are very good people, they do a excellent job. If you need of any information or help you can count on them.
