In short words: great location, easy check in and perfect communication. Ryan answered very quick.
A bit difficult to climb up to the second floor with luggage . The stairs are stiff and narrow. The apartment is very light. Everything in you need. Very short distance to the sub, less than 5 min. Stores in Kings cross and St. Pankras, restaurants and bars across the street. Perfect for a short trip for two people. I will stay again.
