Bill is an excellent host. I did not meet him in person but he checked on us throughout the stay. He was prompt, polite, and accommodating. The flat is in a peaceful residential area. It is close to many restaurants and grocery stores. There is a COVID testing site nearby for those who need testing to fly home. It is also close to the District tube line, which goes to many tourist attractions as well as Paddington train station. Overall, Bill's flat is such a good choice that we stayed twice.
