Overall I had a good experience with the host - quick to respond/provide new blankets - but would not choose again for the room. It is not immediately clear from the pictures that this is a small room with mattresses on the floor and plastic tables and chairs for furniture. The entrance is also through a thin (but well-lit) alleyway, which can be intimidating late at night. However, by Cambridge standards, it is a renovated room with nice flooring and re-painted walls. The central heating was also great, and I always felt pleasantly warm despite a visible draft from the windows. The bathroom was also well-sized and kept clean in my experience.
For a single traveler this may be of good value, but with the price increase for two travelers, I would prefer to not sleep so close to the floor.
