Lovely little place.
as many previous reviews have mentioned, location is top notch, if you know London at all its perfectly placed for travel on circle, district and central lines, amenities abound around it, lovely restaurants nearby, Kensington high st, portobello rd so forth.
apartment is small and perfectly formed, comfy bed, quiet bedroom.
check in was a little complicated, keys weren't where they were meant to be etc and difficult to resolve without phone data if you don't have a uk phone, but the gent who picked up the phone helped resolve the issue.
all in all an excellent little gem and will definitely book again.
