We dealt with Hostmaker and they were great. As a family with young children this flat was ideal. The building felt safe and never felt uncomfortable walking in the neighbourhood. It is conveniently located as there is an awesome Waitrose just across the street along with numerous coffee shops and restaurants. You are within walking distance to several underground stations and Paddington Station if you take the Heathrow Express. If you have children its a 15 minute walk to Princess Diana's Memorial Playground in Hyde Park or a 5 minute run if you fancy jogging in Hyde Park each day like we did. Flat is well decorated and feels bright and cheery. We appreciated the good quality linens and towels and a well equipped kitchen. Flat was very quiet with its courtyard facing windows, we never heard any other residents. A great stay, I would recommend!
