My wife and I stayed at Harry,s flat in kate June 2015. We were met by his mother and father who made us feel very welcome. We chose this flat as we were visiting London for a few days on our way home from holiday and I needed a car parking space which was ideal.
The flat is small but as a base to visit London it is ideal due to its close proximity to the Undergound (10 minute walk) there is a Tesco Express near to the tube station for essentials and the Castle Pub is also opposite the tube and has a nice beer garden and serves adequate food, so everything you need is nearby.
My only complaint would be that the bed is listed as a Queen size double, it is not and as it has no head board and does not rest against the rear wall the pillows continually fell down the gap, if this can be remedied I would have been very happy for the value for money flat.
