Flat had a good amount of space for 2 or 3 travellers. I was with my adult daughter and having a room each was great. Only oddity was that the bathroom with the shower was off one of the bedrooms which was a little awkward (not really that bad at all) since we had slightly different schedules.
The location is fantastic. A very short stroll to Westminster Abbey, Big Ben, etc. Also, a tube station across the street.
The flat was clean and had all of the amenities that we might need. Fully functioning kitchen, washing machine, hair dryer, etc.
Overall a great stay.
