It was a spur of the moment trip to London with my husband but in in three days I saw as much as a I could. My first impression was how compact everything seemed. Coming from the U.S. where we spread ourselves out, London was very easy to navigate and get around. I walked everywhere so I wouldn’t miss the little things that you can miss when you use the tube. My last day was spent across town so I took a bus; riding at the top deck.
