Alder Lodge Guest House
This small, neat hotel is handy for Cambridge Science Park, and has rooms for under £50. They’re simply decorated, but come equipped with TVs, toiletries and tea- and coffee-making facilities, and most are en suite. Parking and wifi are free. A cooked breakfast can be added to your bill for £5, while guests in a hurry can opt for breakfast-to-go. It’s an easy walk to the centre of town from the lodgings.
