30+ STUNNING Instagram Photo Locations In London (With Map!)
"The Shard has one of the most beautiful and photogenic views over London (if you manage to go on a sunny day, unlike the one when I went and snapped the photo below). My advice for visiting The Shard is to go enjoy the view from the cocktail bar, instead of the viewing floor. As you can imagine cocktails are expensive, however they are only a couple pounds more expensive than the entry ticket to the viewing deck."
