Rosie is the ultimate host. She had sweet touches when we checked in like snacks, fresh fruit and flowers which was just so nice after an 11 hour flight. Rosie answered every question and request in record time. She was local and available to stop by if needed too, which was nice. Her place is awesomely unique and very clean (which is a big priority.) She offered numerous suggestions for places to eat and things to do. She actually has a handbook left on the side table filled with information she has gathered for her guests. Location was great, close to shopping, Hyde Park, restaurants and not too far from the Underground. We stayed for two weeks which could feel like a long time, but staying at Rosie's place just made it feel like a second home. I would highly recommend Rosie as a host and her place in Mayfair as a great place to stay to all my friends who visit London. 5 Stars all around!
