We did not meet Rufus but he and his team are always ready in the conversation. The lockbox was not difficult to find and the check-in instruction was quite clear. The house was in a very clean situation and we enjoyed our three-day stay very much. The location is fabulous, my parents walked around in the St James Park every morning. The tube station is around the corner and you will meet lots of people travel to work in rush hour. The Buckingham Palace and Westminster Abbey are also not far. One thing is for the light sleepers: there are constructing work going on in the next building so noises and chatting could be heard during the day. Be sure to bring your ear plugs if necessary.
