Our first impressions were a bit mixed. The apartment is adequately furnished and equipped but no more. The lack of a wardrobe or any clothes storing facilities means you really have to live out of your suitcases. However, the large living room gives you plenty of room to spread out so we found it quite satisfactory. And you can do laundry which is great. As other reviewers have mentioned, the area is quite noisy with buses passing very regularly until late evening. But we found it exciting rather than annoying. And we loved the outdoor "rooftop" area which we used both day and night as we had good weather.
Whatever the real or perceived faults of the apartment the location is excellent, close to Portobello Road, within a short walk of Kensington Gardens and just around the corner from Notting Hill Gate tube station. It's a great place to live.
