We picked this hotel for the location - it's a block from St. Pancras, and we had a 7:00am train to Paris. There were four of us, and we had the family room. It was small, but adequate. There wasn't any A/C, which made for a long night, as it was rather warm. The guy at the front desk was super friendly and very helpful.

We book this hotel because of its distance from the St Pancras station. The room is very small and we don't really have much space to put our luggage. It is otherwise clean and "cosy" I would say.
The counter staff is friendly and helpful. They have all the different data roaming chip there FOC. You just need to get it top up at the tube station WH.Smith
So DO NOT get the data roaming chip at the Airport as it is a rip off there.
The ensuite bathroom is very nice (it looks very new) with heated floor and towel hanger.
There is this rule that whenever you go out you must surrender the room key. Kind of weird because when you return you must ask the staff for the key again. Kind of inconvenient in my opinion.
Overall experience is decent.

I selected this hotel based on other's reviews on Trip Advisor and the central location in the King's Cross neighborhood.
It was an excellent decision!
On arrival the staff provided a great first impression and then a cozy, clean room and fantastic bathroom.
