I enjoyed my stay at Joanne's place. The communication in advance was really easy, check in and check out was perfect, Joanne even let me arrive earlier and stay longer, as there where no others guests the next day. Joanne herself has a great hospitality - I enjoyed our talks :) also the house was (for british standard at least, haha, sorry ;) ) quiet. I could even sleep with the window opened and earplugs (I always wear them, no matter how silent but normally can't open the window). For London that's a thing, perfect as the room faces the garden.
I would recommed Joanne's place :)
