I have stayed in many hotels around the kings Cross area for business. This hotel is only suitable for a very short stay and although ideally close to Kings Cross for transport the amenities and room are very tired and need of a lot of TLC.
I booked a double en-suite. A few thoughts:
No chair, very tight space, no cupboard, very poor wifi glad I had my own.
Toilet seat broken, shower door broken, intermitten poor water presure in shower.
Decoration poor, no heating they must put it on when it gets really cold. No soundproofing in rooms.
Upside, it was quiet enough, close to transportation, and if you want a room for a very short period of time then this might work for you.
I gave this a try to see what it was like, but will return to my trusted hotels around this location.
