Patsy's place is in a perfect location near train stations and the British Museum and British Library. She is a friendly and helpful host. The room is on a quiet street. It is as described. The shared bath worked very well. Alfie is a quiet and friendly dog (it is nice to be greeted by a wagging tail).
I didn't figure out ahead of time the room was up 3 1/2 flights of stairs, but it worked out well anyway. Also you might want a sleep mask (I used mine) because the window faced east and gets the early morning sunlight. The sunlight is very nice, but sunrise comes early in summer in England.
I would certainly stay with Patsy again.
