Todd and Amy made us feel very welcome. They were always super quick to respond to us and provided clear information. The doors to the studio had codes rather than keys so we didn't have to arrange to meet them on arrival, which worked great for us. Added bonus: no lost keys possible! Inside the studio they had left lots of helpful tourist information and a guide book. The best thing was a personalized map they had made of the neighborhood with lots of recommendations for food, going out and getting around. Needless to say, this being SF, that they were totally welcoming to us as a lesbian couple.
