Angela offers friendly advice on arrival, and will accomodate late check-in (20:30 for me) times if you need them. There is tea and instant coffee, and all the usual kitchen amenities. The oven is partially faulty, but who needs to cook when there is so much to see and do in London?
My only caution is that there is no wi-fi, and data is very spotty in the room, so download all your google map trajectories and podcasts in advance!
