The apartment was perfect for my needs during my short stay. As you can see it's a compact studio apartment - The apartment was clean and communication with Leyla was excellent wand was always ready to respond to any questions I might've had. The wifi was very good, about 50mbps+ up and down if that's important for you.
As for the location, it is about a 7 minute walk from South Kensington station. The museums are very close by also. If you need any basics then there is a local Sainsbury's just a few metres away. Next door is a Japanese restaurant as well as a Gaucho restaurant.
For anyone unfamiliar with London and are wondering about the safety of the location, South Kensington / Chelsea is considered a rather affluent area and you'll be fine walking around there day or night.
If I'm in the area again I would definitely consider this apartment again.
