Very nice flat in South Kensington - both the flat and the location are great. Gina was a communicative and helpful host - self check in was easy and we had no issues or dramas.
The ground floor is cozy but was room enough for our family of four (two teenage kids) to sit - given the location, can't imagine anyone would be trying to eat in all the time but we found it fine for breakfast, doing a bit of work and watching the TV. First floor has two nice bedrooms and bath + toilet, the second floor has a larger bedroom - again with bath + toilet / shower and room for a cot.
Stairs are exactly as the listing says. No issue at all for our family and the photos are clear.
We stayed on 30 degree days and with the windows opened and blinds down the flat was airy at night - really enjoyed our stay
