Great location and felt really secure. The furnishings are thoughtfully chosen and the space itself was nice to spend time in. Comfy bed and good temperature throughout the flat. It was winter when we visited but the roof terrace would be a lovely place to hang out in warm weather.
I will say sound travels through the flat and from other flats in the building (it's a Victorian house so that is to be expected) so if you're a light sleeper you should pack ear plugs!
