A wonderful building in an amazing setting.  It has been restored with high quality fittings and furniture, all in keeping with its period character.  Staff were all pleasant and very helpful.  The only drawabck, and sole reason for giving 4 out of 5 and not 5, is that it is extremely difficult to reach by car because of many one-ay streets and others blocked off with bollards which completely defeated our Satnav.  It took us an hour after arriving near the cathedral, and we spoke to another couple who had been driving around for two hours.  We raised this with the excellent Kate on Reception and suggested that a map, with a route through the maze highlighted, be placed on their web site.
The road layout is so complex that the hotel could consider providing web based itineries for visitors approaching from different points of the compass as a back-up to the map.  The best we have seen provided written instructions together with photographs of the road ahead including direction signs.
