My husband and I stayed here for one night before leaving on a cruise. The hotel is right in Terminal 5 and even if your flight isn't in that terminal, it is a quick ride on the train between terminals. There is a Marks and Spencer near the entrance to the hotel that is handy if you want to pick up any food or drinks. Breakfast was also included at the Sofitel and was very nice. The room was quite large with a big bathroom. Despite being right at the airport, we didn't have any noise from outside. You also can connect to the 'tube' into the city right in Terminal 5 as well. It takes about 1 hr, but it is more convenient than the faster and more expensive option of the Heathrow Express train.
