Be sure to call to confirm the availability of the room that you book. The en suite bathroom disappeared between the time that I booked the room and arrived.
The daily breakfast is a spread of 4 cereal choices, toast and juice. But it's free and is available until early afternoon.
The office staff were cordial and the cleaning staff were very helpful if you happen to run into them.
The overall cleanliness changed from day to day, there are times when you'll encounter sewer bugs but they are few and far between.
It is a 3 minute walk from king's cross station, this is the most important amenity.
