London is one of the most expensive cities

London is one of the most expensive cities in the world to visit, sleep, eat, drink, or just plain live in. There’s no way to sugar coat it. London eats into your budget quicker than Homer Simpson eats into a donut. While there are many ways to visit London on a budget , one of the best ways to save money in the city is to take advantage of the plethora of free things to see and do in the city.
