I stayed at Jasmeet's airbnb about 7 weeks. Jas is an excellent host and was there anytime I needed something. The studio is very nice and actually stands as a place of it's own, since it has its own entrance and no common walls with other property. It is not as big as shown at the pictures, but it is more than enough for one person. Kitchen has all the basics and bathroom too, including good water pressure and plenty of hot water (a bigger mirror would help though). Buss stop accross the road or 2 min walk (to Romford), but you need a full hour to get to zone 1 (practically you have to schedule for 1 hour and 30 min). Tesco, Sainsbury and Lidl are 10 min walk. Harrow Lodge park less than 2 min.
Regarding the washing machine, Jas did the laundry for me and it was fine.
Internet generally worked fine, but for a strange reason I could not maintain long video calls.
Only problem, for someone not used to it, was noise. Main road is just under your window and cars do not actually stop during the night (night bus also). It didn't prevent me from sleeping, but it was there.
