Good value for Cambridge, if you're willing to take the bus into the centre. I stayed in the annex, which I had assumed would be more modern, but was actually very worn and dated, with poor (internal) sound insulation, and highly perfumed smells. The (double) room (11B, 12B, 13B and 14B are all the same size) was cramped.
The main light fitting and (bathroom) heated towel rail were excessively dusty. The heated towel rail was broken, and a clear electrical safety hazard - it was off, but the switch appeared to be in a public hallway. Oddly, there was a (locked) door from the hallway into the en-suite bathroom.
A minor complaint is that there was a Bible in the room.
The location does get a fair amount of noise from the M11, but it isn't an issue with the windows closed. You do hear everything in adjacent rooms though.
