Michelle was very kind, thoughtful and helpful. The apartment was clean, very close to the center, the bed was a little noisy (but comfy!) and the toilet takes a while to flush properly but it is okay. However, there was an incident on my first morning there because Michelle's son was staying there as well and he was very sick. Unfortunately, the walls are very thin and he was violently throwing up so I could hear everything quite loudly. It wasn't the nicest way to wake up.
I asked Michelle on my way out if I should be concerned and she said he was just hangover. I decided to stay and after that everything was fine.
Beside that experience, I would recommend staying there. I enjoyed Bethnal Green, the flat was close to the tube, there are many shops and restaurants around, the park is pretty during the day (avoid during the night!) and Michelle is a kind woman.
