The location was great - very convenient, close to the tube, easy to navigate to, and had a grocery store and restaurants within a few minutes' walk - and it felt totally safe.
Carol and her staff were readily available to answer any questions or concerns. And after an exhausting day of sightseeing, the kitchen had all the features we needed to make a quick dinner and watch Netflix when we just couldn't do any more!
Note: It is up 3 flights, so be sure you can carry your luggage.
