The room seemed bigger on the photos than in reality, but suitable for one person.
There was everything you need for a short stay. Kitchen was well equipped.
The furniture is rather of the "student-shared-flat-kind-of" type, so really basic.
The room is not really soundproofed, so you can hear anyone going up or down the stairs (which is just the host and her family). The street is really calm, shopping is easy to reach by foot.
There's a good bus connection towards Northolt tube station and Hayes-and-Harlington train station. You'll still need roughly over an hour to reach London city centre. But you're probably aware of that before you book.
