I had a decent stay at Shoma's place. While I didn't love it, it is very good value in London. The host was there to see me in when I arrived to let me in and orient me. They were also helpful in planning my departure the following day. I was unfortunately unable to get a warm shower, but the host reassured me that there is warm water I just hadn't used the shower correctly. I suggest asking ahead of time how to get the warm water to work.
