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.
The apartment (room 14) was compact with a bedroom, kitchen/diner and shower room. It was situated with pleasant views of Parker's Piece and equipped with everything we needed for a short stay, although my eldest found the futon a little hard. There was a problem with the hot water during our stay but this was promptly resolved when we brought it to their attention. The apartment is a short walk to the centre of Cambridge and we had a very enjoyable stay.
