I ended up stayed at this nice room for 3 weeks and i am glad that i chose this room to start my London Life here. It is incredibly clean, tidy with big Sainsbury and M&S Food Hall nearby. No direct tube to city centre but the bus 134 is 24 hours.
Martha is super nice and I finally understand why all people are commenting that in the previous stays. She is a very nice and lovely host.
Alexandra Palace is around the corner with 15 mins walk. Super beautiful secret London spot.
