"There is a covered walkway/bridge to the hotel from the airport. It took me a while to find it, because the signage wasn’t obvious, and it wasn’t clear in the hotel info (I think it’s referred to as the ‘pod’?).
This was totally not the hotel’s fault. My flight got in just before 11 pm, and there is no one at Heathrow to help with information, and also no taxi service (which I thought I needed). I’m pretty familiar with Heathrow, and have taken buses, Tube, and taxis to and from there on numerous occasions — which was good, because I had to change terminals to get to the hotel!— but that night was one of the two worst airport experiences of my life. When I got to the Premiere Inn, the staff were so helpful, and the room so comfortable, that all the frustration from the awful LHR experience just disappeared. Oh— my bathroom also had the most luxurious deep tub. I’ll be making this my go-to hotel at Heathrow"
