The Caley
The Caledonian (or "Caley" as it is referred to by the locals) is Edinburgh's original railway hotel. It has managed to retain much of its original grandeur without becoming over-modernised or too faded. There are big sweeping staircases, wide corridors, and large high-ceilinged rooms with chandeliers.
We paid a bit more than we normally would to stay here (GBP130 a night, which included dinner on the first night), but were pretty pleased with it. The room was big, with a good-sized comfortable bed and a bath, and the staff were polite and helpful. The location is pretty good. Although not quite as central as some other hotels, it is very convenient for buses.
Breakfast was excellent, with all the usual stuff plus a really good hot selection including great fried eggs (nice and runny), and black pudding, although the haggis was rather disappointing. And if you like porridge - they serve whisky with it! Just don't get seated in the overflow annex room beyond the main kitchen serving area - it is ghastly, dim, stuffy and pokey - really sub-standard (but the only negative thing about the hotel). If you get put in here, complain, or wait for a table in the main restaurant/conservatory part, which is rather nice, and was actually once part of the railway station platform area.
We had dinner in the hotel restaurant on our first night (part of the package), and it was pretty good. The hotel bar was very friendly, and had an excellent selection of whiskies - with bar staff who seemed knowledgeable enough to guide your selection (even though none of them seemed to be Scottish).
All round, this was a good, if slightly expensive choice, and we would certainly recomend the Caley if you can get a good deal online.
Unique Quality: All the usual facilities you get with a Hilton in a historic, characterful building. Plus they serve whisky with your porridge at breakfast.
