"This hotel is at Heathrow Terminal 2. The Runway Bar is an excellent place to eat and drink with a fantastic, panoramic view of the entire airport.
The hotel is accessed by walking through a multi storey car park from Terminal 2, which is not very elegant.
However, it is a LONG walk to Terminal 3. Back through the car park. Along to London Underground (at least 400 yards), Then along from the underground to Elizabeth Line and Heathrow Express smoky 800 yards, then another 400 yards from there to Terminal 3. An athlete could do it in 10 minutes, if they ran. For most humans, with luggage it is at least 20 minutes. It is wrong to describe this as Heathrow Terminal 2 and 3. Terminal 3 can be reached on foot walking nearly a mile."
