Very warm and nice place very close to Kings cross (5min walk). Imogen was really kind with a warm welcome and good advices, we almost haven't seen her during all our stay.
To be noted that we can smoothly ear the subway (normal considering that we are close to the station. But this noise isn't annoying at all. If you're sensitive I will recommend earplugs.
Will definitely recommend this place is you would like to visit London for the first time.
