I really like Staybridge Suites, 2nd time I stayed. I did have a couple of issues, I was put into an accessible room(not requested) it was just a bit difficult having shower because there is a fitted seating area which makes it a bit difficult to stand under shower. The room was quite a distance from the lifts down a carpeted hallway which would be a bit difficult if in a wheelchair as well as microwave being high(Im mentioning this because it is an accessible room). There is obviously air fresheners in the hallways, I personally found the smell to overwhelming.
Staff were excellent in all areas. Breakfast is a complimentary buffet with hot food, pancakes and continental. For a free breakfast, it was very nice with good options. Location is good for Heathrow, Hoppa Shuttle picks you up and takes you back to airport for a £6.80 charge. Evening meals available from Holiday Inn right next door.
