I recently stayed for 2 nights on a business trip. Staff was extremely courteous and attentive. The physical facilities are beautiful and well appointed. The restaurant had a wide selection of menu items. Breakfast buffet was top notch. Room was comfortable and had lots of outlets/USB slots for charging. Wifi was good. Fitness center was large and had a lot of machines. Would have been nice to run outside, but there was really no place to do so as the hotel is adjacent to the airport.

Overall, super convenient location attached to LHR Terminal 5, easily accessible for free on Heathrow Express. Getting to the hotel can be confusing as Heathrow Express also goes to central London, which does cost money. There are also signs for the London Underground, which could provide free transport to Terminal 5 but you need a either a UK based bank card or a subway card to access the platform, neither of which I had as a visitor from overseas. But staff are friendly and will answer questions and you can figure it out.

As things are rather spread out, do give yourself plenty of time to get from the hotel to your departure terminal and gate. I was departing from Terminal 2 and it took me about 1 hour to go from the hotel to Terminal 2, go through security and reach my gate, and I was walking briskly the whole way.
