It's very simple -- if this listing is available, stop looking and book immediately.
It's a short walk from the train station, in a lovely Georgian block across from a park. Diana's place has everything you could ask for. Full kitchen and 1.5 baths, 2 comfortable bedrooms, and a large drawing room to draw in (thats what my artistic kids did there anyway.) There was a room to watch TV in too. it is a big place!
Diana was a memorable host. She met us there for check in, gave a quick tour and provided her number in case we had trouble. She also pointed out that her wifi signal reaches the front door of the building which was helpful to me since airbnb only worked for me on wifi.
