Ok stay if you need to be centrally located in London. Close to tube and train station, area has a great lunch market (street food in Leather Lane), and you can walk to most places you need to be in London.
Flat itself is small - narrow hallway and tiny bathroom, short bed in bedroom, can hear traffic very well in bedroom. Kitchen does come equipped, though. Apart from that, I'd note that the tiles on the bathroom floor are broken, there is no water pressure to speak of, and the sofa bed is partially broken.
Note that listing refers to a lift, but know that lift only goes to fourth floor and apartment is on fifth floor, meaning you'd need to be able to get up three short and narrow flights to get in.
So would recommend if you're only one person or a couple. It's not suited for children or groups. It's great if you mostly need it for the location, less great if you plan to spend much time in the apartment.
Check in and check out went very smoothly.
