Last summer my goddaughter and her mum visited me here in London for the very first time. They were here for four days, so you can imagine that we had a rather full schedule to ensure they see the best of London in just four days.
Needless to say, four days is nowhere near enough to really see and experience all of London, but it is just about sufficient to give you a first overview and visit at least some of the most famous sights of London.
So, if you are planning your first trip to London, maybe this four-day itinerary for London might come useful.
Obviously, you can switch and swap as much as you like, no need to stick to a certain order or completing it all.-
