Definitely the best B&B I've ever stayed at! It was a little more expensive than my normal accommodation choices, but was well and truly worth every penny.
The owners, Rick and Sue, have perfected the art of being around when needed, chatting cheerfully at breakfast and greeting guests on arrival - without hovering unnecessarily. The house itself is beautifully decorated in a comfortable style - ie, it's not the sort of place where you feel awkward touching anything in case you break or dirty it.
There are only three bedrooms, but Gallon House is run with the professionalism of a much larger establishment. The room I stayed in had lovely views across the river, with an attractive bridge to one side and the picturesque ruins of Knaresborough Castle further away on the other side. I believe the other two rooms also face the river and have attractive views, but can't vouch for that firsthand.
If you're travelling by public transport, this place is a blessing - when they say '30 seconds from the train station', they mean it. As you emerge from the railway station, you can see the Gallon House sign - it's literally just across the road. This is a blessing when you are hauling heavy bags; I worried at first that the noise of passing trains would be disturbing but whether because of clever building design or scarce trains at night, I never noticed it at all.
The centre of Knaresborough - and all its main attractions - are well within walking distance of Gallon House, and (though not well known or dramatic) make for an enjoyable day's exploration. I spent one whole day doing exactly that, then spent the following day visiting Fountains Abbey (an easy bus trip). Public transport connections from Knaresborough seem quite good; I'd researched other places I would have liked to have visited but couldn't due to time constraints, and buses/trains served most of them.
The food at Gallon House was divine - more than you can possibly eat for breakfast, and optional dinners you can book if you choose. I didn't take up the dinner option (I wish now I had), but the breakfasts were to die for.
The room I stayed in was very comfortable, with a lovely bed and a window seat looking out over the river.
In short: if you're considering visiting Knaresborough - or surrounding towns such as Ripon or Harrogate - seriously consider a stay at this lovely little B&B. You won't be sorry.
