I should say that I'll give 5 star for the staff. The one I met that day is very nice. And you could easily tell that the atmosphere here is warm and friendly. To be honest the facilities are limited. But you could see that they do try to make the best of it. Its about 8 min walk to the tube and the door is indeed hidden. You get clean sheets from staff ( so you are almost sure that they do clean the sheets unlike some hostel I've been to) . Anyway, for the money you paid its worthy.
