Buckingham Palace, Queen Elizabeth's II residence, is one of the most monumental sights you shouldn't miss during your stay in London. Worth checking the change of guards schedule - we went on a Sunday, and it was a unique experience! Heading towards Trafalgar square, we passed St James's Palace, the oldest royal palace in the UK. When we arrived at Trafalgar Square, we were impressed by the beautiful statues and fountains. We then passed Leicester Square, and a few minutes away is the Piccadilly Circus, one of the most famous destinations in London. Big advertising screens, Eros statue, street artists performing and a vibrant vibe. We then went to Regent Street - beautiful buildings and stores from famous luxury brands. On our way to Oxford Circus, we passed through Carnaby street where you can find even more shops. The street decorations were beautiful, and there were many options for shopping, food and drinks. Walking along Oxford Street, we passed through St Christopher's Place, a charming alleyway with cafes and restaurants and finally ended our walk at the Marble Arch, which is located at the beginning of Hyde Park.
