Probably the cleanest place to stay in my experience.
Very pro-active communication and when i to extend the stay the host went out of their way to help me accommodate.
Also, worth mentioning I always find most hosts use cheap beds and mattresses but
the beds and mattresses at William’s place were the most comfortable (better than 5 star hotels) which helps after a long day of work/sight seeing etc.
Only feedback i’d say is lack of low light/lamp the rooms have 3 bulbs and at night its either too bright or pitch dark.
Def. stay here again when i am in San Francisco.
