I love London City.. old buildings are being preserved nicely. A lot of historic places available in London.. a perfect place to visit over and over again..
Get a hotel or rental AirBnB in a suburb. The train system is awesome, so save yourself the extra money and don't stay in a shoebox for $300/night.
There's no city quite like it. If you're visiting England, don't miss London.
Amazing city with so much history. Easy to get around for how massive it is. Food EVERYWHERE. Adventure everywhere. And free stuff to do all over the place.
