Most of the visit was fine but felt scammed by the front desk assist and airport transit. They said it would be flat rate 65 pounds to Heathrow. Cab arrived and said 70 because we were at terminal 5. When we got to the airport the driver said that was a special "cash only" discount so we ended up getting charged 75 pounds. I think they have a scam going on so beware and arrange your own transit.
