If you're looking for a place near King's Cross, but not quite as busy as the main area around the station this is a great place to stay! The rooms are clean, lovely and it's reasonably quiet at night.
If you're planning on spending a lot of time in your room you might want to look for something else, but if you're planning to be out and about a lot and mainly need a place to sleep (and sleep comfortably!) then it's a great option.
Lovely hosts, very clean (room, bathrooms, kitchen). Everything you need, really.
