One of my favourite cities
I love London. I've been all around the world and I'm always drawn to London. Lots to do and see, one of the best metro systems in the world. Found folks to be friendly and helpful. Great shopping, easy access to food from all around the world, and just very tourist-friendly in general. I was traveling alone but I never felt unsafe.
Insider Tip:To save money stay outside of the city centre. The tube is so easy to use, it's worth saving a couple hundred dollars on accommodations. Definitely check out the WB Harry Potter Studio Tour if you're a fan of the series - book ahead, you can't buy tickets at the door. Check out the Borough Market for lunch and take a bread making class in the afternoon.
