The flat is perfectly situated: communication with all the major London attractions is great (by tube and by bus, which allows you to see the city while travelling), but the neighborhood is quiet and peaceful, though there is a pub or two nearby, if you want to have a pint or a burger. The room is spacious, the bed comfortable, the flat beautiful, the view from the roof inviting.
Lee was there to welcome us and show us around the flat (though we arrived in the middle of the night!) and left for the weekend the next day, so we had the whole flat to ourselves! He did come back on the last evening, so we had a chance to chat and to meet his kids, which was great.
I would recommend staying with Lee to everybody - I am certainly going to come back again!
