Our favourite rooms
With floor-to-ceiling windows in most rooms, it's a crime against viewpoints not to go as high up the hotel as possible – stick to the north or east ends of the building if you can. We were wowed by the objêts-d'art-dotted Master's Penthouse Suite on the sixth floor, which has two glass walls, a long balcony where you can ogle Cambridge's most famous bits, and a colossal four-poster; a room made for dirty weekending. The smallest rooms, Graduate Doubles, are on the weeny side, but fine for a quick city stay.
There's no pool, but bring swimwear if you fancy a soak in the spa's river-view Jazuzzi.
With historical architecture (and architectural history) around every cobbled corner, a camera is obligatory. Don't forget swimwear for the Jacuzzi. If you plan on punting the Cam (and you should), bring clothes you don't mind getting damp. NB No one really wears mortarboards.
All public areas are accessible to wheelchair users, all bedrooms are accessible by lift, and some have been specially adapted for mobility-impaired guests.
This hotel is better suited to couples - leave the children at home!
