So we are all very used to the Premier Inn brand. Solid rooms, comfortable beds and you know what you are going to get. Now their sister brand "Hub by Premier Inn" are starting to crop up in a number of locations. With 7 in London and 2 in Edinburgh these are aimed at the city centre traveller who won't be spending as much time in the room - more out and about the city. However this shouldn't distract at all from what is a great hotel... Just off the main Royal Mile (and ironically situated next to a Premier Inn itself) you'll find the hotel. It's a 15 minuet walk to Waverley station and about the same to places like the Castle etc... This of course depends how much…
