We (6 German women and 1 Brit woman) stayed at Susan´s place at the end of October for 3 nights. The house was brilliant. Close to tube and shops, comfy and warm. It is exactly as described. Liason between Susan, airbnb and myself was totally without any hitches.
The location for Stansted airport was fantastic and 30 minutes to get into the centre of London. Wanstead feels like a respectable, safe place and great for breakfast before hitting town. Can recommend the first cafe on the left which was brilliant for an English breakfast. There are plenty of banks, supermarkets, chemists and eating places all within easy reach of the house.
