Catherine is very responsive and her apartment is situated in a quiet street despite being close to ground floor. The building and interior is old but she has spend a great amount of effort to refurbish the apartment into a nice and modern looking space.
Walking distance to King's Cross station with many shops and dinning options available. There is even a weekend market nearby which I didn't know until Catherine had told me about it.
Do note that you will need to climb a flight of stairs to get to the apartment.
