Only one (major) thing wrong
Everything good about this, except the pair of large and very loud extractor fans in the courtyard outside our room which stayed on all night and made it very difficult to get to sleep. A real disadvantage that brought down what would have been a near-perfect stay. Once we had turned in and realised the problem there was no-one was available to contact about this, except an emergency number which we were reluctant to call as this wasn't, strictly speaking, an emergency. If you're the type who can sleep through anything this place will do for you, and those rooms not overlooking the courtyard are probably perfect, but if you need quiet for sleep think twice about the Old Bell.
