You can expect a place that need a bit of cleaning done and some work done aswell. However my room lived up to my expectations and if you just need a cheap place to sleep while you explore London this place does the job. About Simon as a host, I really cannot say much, if you do not seek the contact, he/they will just leave you to it, you're in control in that way. Lastly you share the house with other users of Airbnb, which means the bathroom may be occupaid from time to time and you will hear the other guests walking up and down the stairs.
