An excellent basic hotel in typical British tradition. Small comfortable rooms with well-designed, well-equipped shared bathrooms. Nice modern shower arrangements kept immaculately clean. Regency Guest House now operates without reception: room keys are ready to grab as you enter. My single room was warm, tastefully furnished, and cozy with a big beautiful tree out the window and a park beyond. The walls are thin, and there's a pub next door that may be busy and loud (including in the wee hours when a night's bottles get recycled). Ear-cancelling headphones or earplugs recommended. But other than that, the location is extremely convenient, halfway between the train station and central Cambridge, and the hotel was a delight.
