London travel tips

1) Londoners speak with a peculiar accent that is difficult for tourists to understand

Even if you speak excellent English, it can be difficult for you to communicate with the locals in London who speak with a peculiar accent. Indigenous Londoners speak English that is incomprehensible to tourists (for example, the famous Cockney dialect).

2) Get a 180-meter view of London from Mary Ax 30

The Mary Ax 30 skyscraper has become a symbol of modern London. This is a 180-meter-high building of original design: it expands from bottom to top and then tapers towards the top, due to which it throws a very little shadow. Due to the unusual greenish colour of the facade panels, it is called "cucumber". On the ground floor, there are boutiques, and the best restaurants in the city with an observation deck are on the top of the building.

3) Most museums in London are free. For paid attractions, it’s more profitable to buy tickets online

Many museums in London, such as the National Gallery, British Museum, Victoria and Albert Museum, and others, offer free admission. Because of this, there are long queues at the entrance to the museums, so arrive early. If you decide to visit a paid attraction, buy tickets online – it will be 2-5 pounds cheaper.
