To be entirely fair, there are some good features here: the location is ideal for Glasgow City Centre and Taxis are available right outside the door. The building is a glorious old Victorian Railway Hotel forming part of the Glasgow Central Railway Station, ceilings are high with 3 flights of stairs between floors. The rate charged appeared reasonable for the hotel's rating and location (assuming you don't pay advertised rates) but, sadly, the hotel was generally very tired-looking. Being so huge, it will take an enormous amout of money to improve, but it also felt quite dirty with a sticky, 'working men's club' aura about it and there's no excuse for that.
My room overlooked the station concourse and had secondary double glazing to muffle the announcements and drunken shouting - it was effective enough, and it also stopped any smell from the decomposing take-away food containers left on the window-ledge by a (long?) previous occupant. The room itself was acceptable and, although the plumbing was a bit victorian, there was plenty of (slightly brown) hot water. I was rather surprised to find my room open with workers inside fitting A/C on coming back in the afternoon - they were very polite, but I did think the hotel should have warned of this or, preferably, left the rooms concerned vacant on the day of the work.
The Full Scottish Breakfast, self-served in the uninspiring dining room, was of poor quality all round: rubber eggs and cheap sausage headlined the greasy-spoon cafe cuisine, whilst the fruit was tinned and the croissant and danish pastries were poor imitations. Even the Scots' signature dish of porridge looked grossly unappetising. I can't fault the choice however, other than I preferred to choose very little of it!
The bar was very austere with spartan furniture, no carpet and was quite smoke-filled considering it was so quiet, whilst the Murphy's on sale, unlike in the advert, was bitter (uk readers only!) and had to be returned. It appeared that the cellar pipework was no cleaner than the rest of the place. Finally, as we left after breakfast we had to step around a 'pavement pizza' (vomit) left on the threshold by a late night reveller - not a great farewell, but such an appropriate warning to new arrivals that I wish they'd thought to place one there on the day we were due to check in!
There were 3 AA stars on display in the unwelcoming lobby, dated 2005, so I won't be keen to take those as a measure again - it caused me to wonder whether the cerificates are worth the paper they are printed upon.
In sum: the location was good, the room was ok, but the everything else was poor. My advice would be to avoid this down-at-heel hotel if you're a traveller; if you work for the AA you might wish to review your assessment before your own credibility is damaged.
