London Heathrow Marriott: the full-service Bath Road hotel

The London Heathrow Marriott stands on the Bath Road at UB3 5AN, the A4 strip of larger hotels immediately north of the airport, about two miles from the central terminals. That puts it in a different category from the walkway hotels: you do not walk to check-in from here, you ride. The Hotel Hoppa shuttle runs from the hotel to Terminals 2 and 3 on its most direct route, and on another route to Terminals 4 and 5, at £7.00 single and £13.00 return per adult, roughly every 10 to 30 minutes across the day.

For a cheaper transfer, the Transport for London buses 105 and 111 run the same Bath Road into the central bus station between Terminals 2 and 3 at £1.75 a journey, around a quarter of the Hoppa fare, with the trade of more stops and less room for bags. The hotel is closest to Terminals 2 and 3, so it suits a Star Alliance departure from T2 or a Virgin, American or Emirates flight from Terminal 3 best; from Terminal 4 or 5 you would be crossing the airport, and the which-terminal lookup is worth a check before booking.

The Marriott runs 393 rooms over five floors, built in 1998 and refurbished in 2018, so the fit is current four-star rather than dated airport-hotel. Rooms are soundproofed against the Bath Road traffic and the aprons, air-conditioned, with the usual full-service kit, a proper work desk, a decent bathroom, and the space a budget hotel does not give you. Grades run from the standard Deluxe rooms up through Executive rooms and suites, with family options and accessible rooms across the range.

The M Club Lounge is the executive lounge, open to guests in the higher room grades and to Marriott Bonvoy elite members, with complimentary drinks, breakfast and light food through the day and a quieter space to work. For two people travelling together it can offset a good part of the rate through the food and drink alone, and it is the sort of feature the Bath Road budget hotels do not carry. On a one-night stop before an early flight the standard room is usually enough; the club grade earns its place on a longer or more leisurely stay.

The feature that sets the Marriott apart from the rest of the Bath Road is the London Heathrow Marriott Leisure Club: a heated indoor swimming pool, a gym, a sauna and a steam room, free to guests, with the pool open roughly 06:00 to 23:00. Most airport hotels stop at a small gym; a genuine pool is rare this close to Heathrow, and it is the reason families and anyone with an afternoon to fill before a night flight pick this hotel over a cheaper bed nearby.

Dining is three outlets led by Carluccio's, the on-site Italian restaurant, with a lobby bar and lounge dining alongside, and breakfast in the main restaurant. The honest caveat is the one every airport hotel carries: the food is convenient and priced for a captive market, and for a cheaper meal the terminal's own restaurants are a short Hoppa ride away. What you are paying the Marriott for is the pool, the leisure club and the full-service comfort, not a cheaper plate, and on that it delivers what the walkway budget hotels cannot.

The Marriott has its own car park, around 250 uncovered spaces, with on-site self parking at about £25 a day, and it sells a Park Here, Fly There package that bundles a night with discounted parking and return airport transfers. That makes it a genuine park-and-fly base as well as a hotel, which is a large part of its Bath Road business: leave the car, sleep, and be shuttled to the terminal in the morning.

The maths deserves a check before you book, though. For a night plus a week or two away, the nightly £25 parking rate is the wrong tool; a Park Here, Fly There bundle, or a room plus separately booked airport long-stay parking, both work out cheaper than feeding a daily rate to the hotel car park for a fortnight. The package comparison sets the bundle against the alternatives so you can see which wins for your dates.

Book the Marriott when you want a proper hotel rather than just a bed near the gate: a family that will use the pool, a leisurely night before a flight where dinner and a swim are part of the plan, a park-and-fly with somewhere comfortable to sleep, or a longer stay that a budget room would make a chore. For a Terminal 2 or 3 departure it is well placed, a short Hoppa ride from check-in with the facilities to make the evening worth something.

Skip it when the walk to the gate is what you are buying. For the earliest flights, a walkway hotel beats it: the Hilton Garden Inn for a T2 or T3 departure, the Premier Inn at Terminal 4, the Sofitel at Terminal 5, all of which put you minutes from check-in on foot. And on the same Bath Road, a Premier Inn sells a cheaper bed and the same Hotel Hoppa for a traveller who does not need the pool. Set the options side by side on the Heathrow hotel guide and let the terminal, the budget and whether you want the facilities decide.
