You can expect a tidy but rather small room. The bed is about 1.90 m long, so for tall people it is a bit short. The toilet and the shower is shared with two other rooms. Same is true for them - tidy but rather small.
Towels etc are provided as announced. The staff is very helpful and hospitable.
Location is very close to King‘s Cross but not noisy. Walls are rather thin so you can overhear your room neighbours quite easily.
