Location, value, cleanliness, were all good. It was one block away from the shops and restaurants on Queensway, a great shower/bathroom, and walking distance to the tube and areas of interest.
The only issues were: it was darker than in the photos (well, it is in the basement), and if you opened the blind you looked into the window of another suite. I would recommend getting a similar unit but on the ground floor or higher.
Otherwise, we enjoyed our time in London, in the suite.
