We stayed here for 8 nights and it was great. We are a family of 4 - 2 adults and an 11 year old and 17 year old - with visitors for a couple of nights of another adult and teen. There was plenty of space for everyone to spread out and have alone time, everything was comfortable, and the apartment was well stocked. It is an easy walk to and from Kings Cross station, which made it very easy to get all around town. The subway noise is noticeable but not at all disruptive. Our light sleepers had no issues sleeping through it and after the first night or two we didn't even notice it anymore. We would definitely stay here again.
