Connie's house is beautiful and packed full of culture and history. The location is fantastic: in the Castro near easy Muni access and in walking distance of the Mission and BART. I read the other reviews before staying here and I think they were broadly representative; every house and host has its quirks. I'll add:
* This place is fine for people with mild cat allergies. I have a mild cat allergy that was not at all triggered during my week-long stay. The room was clean and cat-free.
* I found the bed to be soft and comfortable.
* Connie provides a lot of information about SF, takes house rules seriously, cares very much about receiving 5-star reviews.
