I contact with Kamal, his response is fast and flexible. I met Kamal's assistant, Hussain. He is a warm guy, helped me to keep my luggage somewhere in the house for a couple of hours after I checked out.
The house is very close to Shadwell station, which is convenient. It was a bit noisy outside sometimes at night probably due to Saturday evening, but it was ok for me. In general, it was a good stay.
