This is exactly what you think it will be. A small clean room with crisp white bedding with the sole purpose of being close to the stations. We had a twin room on the second floor and the beds were ridiculously comfortable. There was a sink in the room as well as a mini desk with some small tea bits and a kettle. Plenty of plug sockets including USB sockets. It is a shared bathroom with a toilet being the first one (this one is quite small and dated with only cold water in the sink) but down the bottom is what I can only describe as the shower of dreams. White marble, huge mirror, powerful shower and everything with super clean. Lovely 2 in 1 shampoo/body wash and additional conditioner provided. Clean white bath mats.
They also let us do an express check out by just leaving the keys in the room as we needed to be out by 6am to get the Eurostar. This information was added to our booking when we checked in.
Please note that if you book this hotel you will check in with the (much swankier) hotel next door and get taken across by the lovely receptionist.
Genuinely will be coming back here whenever an overnight stay near St Pancras or Kings Cross is needed!!
