It's a great location for Kings Cross/St Pancras. The breakfast is decent; continuous drip coffee available (ask for (hot water for tea), a good hot breakfast selection, some pastries (croissant and Pam au chocolate), bread for toast with jams/preserves, and cereal.
The room was a bit small. An Italian style shower (just enough room for one), a slightly small bed (both length ways and width), with a slightly disconcerting room door that opened outward. Not that there were any issues with that, especially with a door code for the hotel entry.
