Hello,
I am planning to visit London in August and I am wondering if you have any suggestions of cool places to see, like kind of unforgetables places that can't be found in tourist books, random secrets places only known by the familiars of the city or the old wise Londoner that knows all the recesses and history of the city (Ok, its maybe a little bit exaggerated )
Otherwise if you have nothing of this, just tips of spots that must be seen in a trip in London or reads that covers the subject and worth reading.
Thanks you for your help ! (English is not my native language so sorry if there is some mistakes)
