We had a comfortable and relaxing stay at Kay's house. The location really is perfect, within a very short walking distance of the Underground/bus, park, cafés, museums and so on. Despite being so central, the room itself is an oasis of calm day and night, even with the windows open. Kay was flexible and helpful at check-in and we felt welcome. The rest of the time it felt like we had the place to ourselves, and could drink tea and make plans in the mornings and evenings, use the fridge, etcetera. Having a private bathroom is another advantage as we felt like we could do what we needed to do, anytime, without being in the way. All in all, this is a very convenient, affordable and easy place to stay for a few days in London.
