I stayed at Kate's house for 5 nights and had a great experience. Kate is a perfect host, very kind and generous and attentive. The room is very clean, spacious, and comfortable, and the neighbourhood is perfectly safe. It only takes a few minutes to walk to a bus stop where you can catch a bus to Ealing Broadway tube station (Zone 3). Buses come every few minutes, so it's very convenient. I highly recommend staying at Kate's place!
