Due to line work on the Piccadilly line at weekend, we were not able to go from Heathrow directly to Central London. There was no service between Acton Town and Hammersmith. Our journey ended up as follows: Heathrow to Acton Town transfer to District Line, Acton Town to Ealing Broadway Transfer to Central Line, Ealing Broadway to Bond Street transfer to Jubilee, Bond Street to Swiss Cottage.
Two hours later we were at our hostel. Originally, we were trying to figure out what to do with our luggage prior check-in since we had around 3 hours to kill. As it turned out, we arrived just as reception opened.
