We were staying for a week at this apt and we loved it! Lots of design details, books, fully equipped kitchen that made us want to host friends over. Bedroom was large, the bed was giant, spotless clean and comfy.
we read a review here that raised some concerns but we found that most of the things were either fixed or non-issue.
The location is so-so, we took advantage of the weather and walked a lot, underground is 12 min walk and there are some bus station closer. Neighborhood is peaceful and quite. I don't know if I would recommend it for a classic first timer to London, but the apt itself is just so cozy well designed and well equipped, we really felt at home every day's end (gave us design inspirations for our place).
