I stayed at Izzie's place for about five weeks. Izzie was nice and helpful, and I had smooth communications with her.
A big advantage of the flat is that it is quite independent: it is self-contained (a private shower and toilet, microwave, kettle and fridge inside the room) and a private entrance. The room was simple and clean. It is located in a calm and peaceful area. Bus station is pretty close (2-3 min walk) and it is about a 15 min walk to Piccadilly line (Sudbury town tube station and the Piccadilly line Uxbridge-Cockfosters every approx 10 min).
Since the flat is in a garden, it can become quite cold in winters. A small noisy heater was provided, but I was generally OK with the room temperature.
