This quiet, beautifully zen-like hotel is truly a calm oasis for weary travellers. Accessed directly from the arrivals level Terminal 5 by foot (exit right, after passing through customs.... down to the end exit opposite Marks & Spencer's), to the dedicated lift one floor up, then it's less than a five minute covered walk and you can take your luggage trolley.
A bang on trend minimalistic hotel, beautifully decorated and exceptionally clean in every area. Staff (many/most of whom seemed to be French) were extremely proactive - offering immediately to take people's luggage and were really friendly and welcoming.
You will struggle to hear any aircraft noise; it is incredibly quiet. There are discreet water dispensers in the corridors.
My room, although not massively large, was more than adequate in size and again, very well furnished in solid, minimalist style with high quality furnishings. The bathroom had a walk in shower and a bath with separate shower head. A very comfortable recliner seat with footstool was also provided in the bedroom. A cooler type refrigerator was also provided with complimentary sparkling and still water. Lights are on dimmer switches. The bed was firm but comfortable. The standard of cleaning is exceptional not just in the rooms, but the hotel looked immaculate throughout. For wifi, there are several options; there is a free connection available (iBahn) but it is very slow. TV mounted on the wall in exactly the right place for viewing either in bed or on your relaxer chair!
Lively "sports" bar downstairs, with atmosphere (but not rowdy - it's not that sort of hotel!).
For anyone seeking a "classy" high end hotel, I think you will not be disappointed with the Sofitel.

We stayed the night before our flight to America the service is second to none we parked in the car park below the hotel for 8 days then get the lift to check in you are greeted by staff to assist you with luggage and show you to a check in desk it's a spectacular hotel 5* luxury the rooms are modern and spacious lovely comfortable bed and no plane noise which is a bonus
Small fridge in the room with complimentary water we ate in the restaurant which was lovely and service and politeness of staff very noticeable there is an open kitchen with very friendly staff at breakfast which was plentiful and a great selection although a bit expensive ( you get what you ave paid for ) its worth every penny for a treat the walk to terminal 5 wasnt too ar and the hotel get you a trolley so no carrying bags

Airport hotels can be the most soul destroying part of the most successful business trip. However, the Sofitel T5 delivers a luxurious experience without being ostentatious, efficiency in check-in and out and a perfect, peaceful and inspiring location within walking distance of T5 and connections via the Heathrow Express. It's not cheap, like so many other sub-standard airport hotels.

I had reason to be in Terminal 5 on numerous occasions both last week and the previous week. Knowing there was a Spa shop which stocks ESPA products I was amazed and very disappointed to find that one each of the five occasions I made the trip to the Sofitel the Spa shop was closed. I don’t understand why a shop in a five star hotel would be closed during normal trading hours… However, I did have a very pleasant experience in the Bradley Smith Hair Salon which was open and indeed stayed open late to facilitate me. Well done Bradley, the salon owner who re-styled a rather tired bleached out hairstyle and I emerged feeling wonderful, re-juvinated and giggling at his great sense of humour!
