This is a great place. The location is ideal and sooo close to transport. Right near Kings Cross and St Pancras stations with Tube lines to all over London, as well as national rail links to further afield. The apartment is quiet even though buses go past all the time (most are electric or hybrid) and there are several great restaurants nearby on Kings Cross Road and Gray's Inn Road. Very walkable too.
It's very airy and spacious for one or two people, and has everything you need for a longer stay (washing machine, dishwasher etc).
