So many postive things to say! We chose this Knightsbridge location, on Piccadilly line for easy Tube access to Heathrow, and bus access both at Harrod's around the corner and on Knightsbridge road a few blocks away. Ambiance in the apartment was total relaxation. Upon arrival opened back windows to hear heavenly choir from church next door. And birds chirping. We were so happy with the high level of comfort at the apartment--plenty of space, gorgeous light, heated towel rack, huge bed in master plus two pullouts for sleeping. Kitchen was super-well appointed with tools for cooking, tea, coffee, fresh milk in fridge! fresh fruit on table, fresh sweets for tea, and more. (a birthday cake complete with candles - extremely thoughtful, thanks again Bob), a TV to watch the Masters Golf tournament, even a few beers in the fridge making husband very happy upon arrival! The care with which the host prepared the place made us feel pampered. Bob is a superb host, answering questions quickly, with good tips / ideas for itinerary for us newbies to London. After day 1, he checked back in via message to ensure all was well with us. It was. He allowed us to drop bags early in day, and took time to point out shops, orienting us to nearby Museums & Hyde Park. Great location for high end shopping. A1 all around.
