The apartment is exceptionally comfortable, clean and beautifully decorated. 10 - 12 mins walk to chalk farm tube station. In typical London fashion it can be the difference of half a street that can change the "feel" of an area and unfortunately this apartment is located on the slightly rougher side of chalk farm - but this is what possibly keeps the price at such incredible value for London. Bedrooms are on street side and are quite noisy at night if you are a light sleeper, however, the beds are very comfortable!
I still rate this place 5 out of 5 despite the location comment which is really just for other peoples reference.
