Mark's flat is clean and well stocked. The fridge was stocked with water, juice and milk..and beer. This was a pleasant surprise! It's in a great location close to a lot shops and restaurants - Sloane Square and Kings Road and is less than 10 minutes to the tube probably closer to 5 minutes. The flat is on the lower floor with a narrow short staircase (typical of these types of homes though) that was a bit tough with big luggage and it also didn't get a lot of natural light. The washer and dryer is not in the flat but just outside of it. Other than those minor things, my family enjoyed staying there. Mark was very responsive throughout the process. We didn't run into any problems during the stay.
