This place is, overall, a budget choice. The location is really good as Kings Cross can take you pretty much anywhere in central London. But other than that, the stay is really average. The environment isn't that clean and tidy. You will be sharing the whole house with some other people, including smokers. The noise, from the stations announcements to just people shouting, can be a bit disruptive. I even had my toothpaste, which I've accidentally left in the bathroom, gone missing. James also went missing during check out.
Overall, if you are visiting London and you don't require much for accommodation, this place would be worth it. But if you are looking for more, you might want to reconsider.
