Time for the overview of London tips! I got to spend five whole days in this wonderful city and it did not, in fact, feel either too less or too much rather perfectly
But back to the real subject. I have listed below approximately how we spent our days in London. My main goal for sightseeing and exploring is to take a full advantage of daylight and walk around outside until the sun light disappears and then move to indoor activities such as museums. Piccadilly Circus, China town, and Oxford Street and its stores are also places which are good evening activities! Some places, such as these three listed above, we visited few times in fact: during a daytime and late in the evening because when you do sightseeing by foot and walk from place A to B, C, D...you will end up to a familiar place in the end!
I usually plan my days ahead by finding places which are nearby each others to avoid going back and forth and instead enjoy what comes on the way while walking from attraction E to attraction F, G, H,...anyway here comes five days in London!
China Town - you can find amazing food here: salty and sweet!
Piccadilly Circus (here you can also find M&M-, Lego-store and many many souvenir shops)
St. Pauls Cathedral

I could tell more about every place listed above but I do not think its particularly necessary but to give a chance to know more (if wanted), shoot a comment if you have any extra questions of these places and want to hear my opinions and favourites!
