The flat was really in good location, close from everything, you walk 10 minutes and you are in oxford street, flat is Cosy and well furnished, big enough for a short trip if you are 2, the only "bad" thing is to go to the office to take the keys, that is a bit far from the flat.
Ali is really nice and gave us a warm welcome, I recommend the flat if you want to go to London !
