I had a very pleasant stay at Jerome's place. He and his co-host were very helpful, friendly, and always available. Thank you guys for your help with my luggage!
The room was clean and spacious, everything is as described. I would definitely stay there one more time if I am ever in London again.
The only thing is that the street is extremely noisy, even late at night. So if you are a light sleeper, it might not be a place for you (it was fine for me, though).
