This is a no-nonsense, small room with a bed and a table and mirror and not much else, in a narrow hallway with 3 other flats sharing a basic kitchen and even more basic bathroom. Not the kind of place you'd stay with your family, but more of a budget option for someone in town for a night or two, or a couple who's going to be out exploring London and not spending much time in their accommodations. The bed and room were clean, the bathroom was a little sparse but did not feel dirty, and I could have used the kitchen and washing machine there if I needed.
Location is within spitting distance of King's Cross station, right in the heart of central London, and though the neighborhood felt safe, the apartment building was nevertheless behind two key-controlled doors. So I never worried about safety or security.
All around, if you need a room for a night or two, great budget value. And the host was EXTREMELY communicative, friendly and responsive. Thank you!
