Location: it is 8 minutes walking distance from king cross work station. You can walk (1hour) or bike (30 minutes) or Uber ($17) to see the the queen palace, Big Bang tower, etc
Place: building is not prime, neighborhood seems rough but I guess it is safe. Room is very small. Not ideal to hang out. Just to sleep in.
Wi-Fi: it is pretty good. I had to work from home few hours and had no place.
