Stay Away!
Stay away from the Picadilly Line until mid-September. Avoid at all costs. I don’t know what I was thinking but I went on it today and it was HORRIBLE. It is the only tube line that goes to Heathrow so it is FULL of travelers going to and coming from the airport. This also means that there is no room for people because it’s full of suitcases.
It kinda looks like that.
