The room was clean and cosy, and the bed extremely comfortable. Location-wise, it's an easy 10-15 minute walk from the nearest Underground station, but noise from the road is a potential issue. Bear in mind there are cats in the house, which I love, though others may feel differently (they did not enter my room or bother me in any way).
All things considered, the room was - without question - worth the cost.
As for the host herself, she is a an absolute star. Stephanie is welcoming, relaxed, willing to help, charming, and overall very easy to get along with. An excellent example of what a good host should be.
100% this will be the first place I try to book during my next stay in the area.
