I enjoyed my stay at Apartment #102 and would consider staying at that same apartment again on another trip to London.
About the basics. The pictures accurately reflect the apartment and it is on a quiet street with lots of light. The kitchen is pretty basic but I did not plan on using the kitchen except for a quick breakfast and snacks, so it was sufficient for me. It is a great location because the South Kensington Underground is a brisk eight minute walk from the apartment and three different lines can be found at this station. Also, there is a grocery store and Starbucks across the store, as well a bus stop. If needed, there are additional bus lines on King Street, which is a quick five-minute walk from the building.
A note of caution about communicating via Airbnb email. It might have been a fluke, but I sent several emails prior to my visit and never received a response. That being said, when I arrived after an overseas flight, the staff was wonderful and arranged for early checkin for me --- calling me when I left for a moment to let me know that the apartment was ready. Also, there is a 24/7 concierge on site which is a really nice side benefit.
In sum, I would consider staying at this same apartment if/when I return to London.
