The room is absolutely to recommend for a short stay in London. It is nice and comfortable and seemingly newly renovated. The shared facilities (kitchen and two bathrooms) were fully equipped and clean. The room itself even appeared to be bigger than it looked according to the pictures online.
Communication with Taylan was easy. We received all necessary information on beforehand. Check-in and check-out went without any problems.
The neighborhood is indeed not the quietest. However, this is what you expect when heading for such a huge and vibrant city as London. Bethnal Green, this is to say, is worth a visit on its own (maybe next time).
