Hers is a very nice place to stay in London with a quiet and nice environment. The next tube stations are close and the walk there allows for a tasty cup of coffee in the nearby bakery. The room with the separate bathroom is excellent. A small disadvantage might that there is no socket in the bathroom and the provided mini-fridge is (in my opinion) too loud to run it during night. Nevertheless, these are no real drawbacks and I enjoyed the stay there very much.
Her lovely dog is a clear bonus and another highlight of the stay.
