Great trip. Flew nonstop from Cancun (four hour bus ride from our home) to London (Gatwick). We were meeting two friends there, who were arriving a couple of hours after we did. We asked around and took a train, the Thameslink, I think, to Kings Cross / St. Pancras. Once there we found a nice restaurant, I think it was named Mi and My, in the upstairs of the station. We had breakfast and started to get texts from our friends.
They met us at the restaurant and St. Pancras (they had flown into Heathrow on separate flights), and we dropped our bags off at our two room flat and then got out of the way of cleaning person. It was about a 5-10 minute walk from the train stations. Found a grocery not far away, on a little canal near Granary Square. Bought some food, ate some lunch and headed back to the flat at 3:00. Got in, unpacked and started recovering from jet lag.
