This room is large--very large for central London--with a bathroom shared by only one other person and pretty good kitchen access. It's a good option for longer stays, where you might need to have a little more freedom and room than you would for just a night or a week.
The nice, large wardrobe with hangers, nice bed, and a table to do work also help. y.
The wifi/internet (as in most places in London) is a bit hit-or-miss. Sometimes it's good; at other times, it's a little spotty.
The location is actually perfect. Literally one minute away from Kings Cross/St. Pancras station; two minutes from the British Library; plenty of shops, stores, restaurants, and services around. Your uber will have no trouble finding the place.
Best of all, Jin, Jacob and the other residents (at least the ones who were there when I was there) are extremely sweet and accommodating. Worth the stay just to make the new friends.
