We never actually met Zehra (I think we barely missed each other a couple of times), but she was very accessible via messaging/email and offered great recommendations for good eats and events in the vicinity. The flat was also at a very good location--it was a 2 min walk from Bethnal Green station.
The room itself was well equipped (lamps, extension cords, a little paper with general info like wifi passwords, etc.) The bed was comfortable, the kitchen well equipped (there's a mini-fridge just for guests). I'd definitely recommend it.
