We stayed at Angie´s für three days. The room ist very small and has a small double bed. The bathroom is shared with Angie. Everything is very clean. Angie was very polite and allowed to leave our luggage in the flat after our checkout, eg.
You cannot get a room nearer King´s Cross Station. From here you get everywehre by tube without any problems. It is no problem that you cannot use Angie´s kitchen as there are hundreds of restaurants and cafés near the flat.
Although the room has a window to the backyard, it is quite noisy at nights if the window is open. But I think you cannot expect to get both a good location and a quiet room.
Thanks a lot, Angie!
