Nice and quiet neighbourhood, very convenient to Camden. I stayed for a week in winter and the little heater in the room kept it very cosy. The room is smallish as described, but it's clean, has a lovely character and has everything you need for a good night's sleep including a comfy bed, plus the bonus of a small fridge, toaster and microwave for some self-catering. It was surprisingly private given it's in the backyard. Margie was lovely and on-hand whenever needed. I was working when I stayed, I only wish I had had more time to chat with the hosts!
My only minor suggestion might be some form of heating in the bathroom in winter, as it's a nippy trip at night between the room and the separate bathroom - I had a warm coat that I put on and that worked fine too. Bathroom was spotless.
