Me and 2 of my colleagues stayed in Ken's apartment over the weekend.
Ken is super responsive, we got super clear instructions about the place.
We slept very well despite being on the main street. 4th floor is quite high above the traffic, so we did not hear the sound of it.
Whitechapel is not the area you'd want to walk at night in, but we were using cabs all the time, so it was fine.
Value for the price is very fair.
Greatful for a great weekend !
