i stayed at Catherine's place for a month, working from home 2-3 days a week. it was perfect for this - the room with the couch, desk and microwave feel spacious and very comfortable for one person.
Catherine is a lovely host, helpful, attentive and generous with fresh bedding and towels every week.
the location is convenient for communing into London - a short and straight walk to Boston Manor station which is on the picadilly line. there is also a sainsburys supermarket on the way, which only closes at 11pm.
the area felt safe, and there is a nice and big park nearby which i went for almoast-daily walks in (walk to the very back, and there's a gate to a much wilder and more natural, bigger park).
the three rooms (bedroom, living room and bathroom are on the top floor of a big house where Catherine and her family lives).
I'd really recommend this place for a long(er) term stay, if you don't mind eating microwaved food (I'd recommend cooked rice from the supermarket, curry, and vegetables/beans/tofu!).
No issues at all, enjoy if you stay here :)
